Was I in the wrong? Neighbour issue?

I suspect the neighbour has had a lucky escape by not being on the group and all the cliquey behaviour involved.

you’ve caused this situation so you need to remedy it. Go round and apologise profusely and explain your ridiculous actions and say you got it wrong and would like to sort it out as you could be neighbours a loooonnnggg time and it’s very hard living with neighbours that you’ve fallen out with!

She used to chat and take in parcels and from this you inferred that she would not want to join a neighbourhood FB group?
You sound bit "mean girl"

Neighbourhood Facebook groups are a thing but three streets worth seems very specific.

That aside, you've simply made a social error in excluding them from the group by assuming they wouldn't be interested in taking part. It's common courtesy if making a group for three streets to give everyone a chance in those three streets to join or they would (rightly) infer that they aren't welcome.

You've created the situation and can remedy it by sending a quick invite and explaining if you miss their cordial greetings that much.

I'd be glad I'm not on the FB group if you have to buy neighbours kids birthday present. Sounds like a nightmare and where will all this present buying end. Will followers be in a panic if they forget someone's birthday or what other time you think they should buy presents.

Exactly. The OP sounds like she has Queen Bee aspirations. You deliberately excluded this couple because of how you perceive them. To suggest it was for their benefit is disingenuous. You saw this couple as no more than your personal concierge. Shallow souls like you, OP, are soon unearthed. You sound rather pathetic.

It should've been up to your neighbour to decide whether they want to join or not. You can't just assume they wouldn't want to. I'm not surprised that they're not bothering to speak to you or taking your bins/parcels in.

You are the problem here

What gave you the idea that they like to keep themselves to themselves, if they take in your bins and packages and they're trotting round with birthday presents and cards for other neighbours?

It sounds like you've made a massive (and incorrect) assumption about them. They're probably not chatting much with you, because they think that you've got a problem with them - and the thing with the FB group has probably confirmed that!

@Grammarnut's advice is sound.

It’s not for you to make assumptions though based on whether you think she would want to engage.

It should be up to her to decide that. So you ask her, if she says no then it’s been her decision, not your unilateral decision to not invite her to a group which she then found out about from one of the other neighbours.

It’s pretty shit really tbh.

Thinking you know what other people think and do has ended more than a few friendships!!

can you blame her? you started the nonsense by not inviting her to what ought to be a pretty-much public group.

in her shoes I'd start a rival one, and invite everyone but you... but i am petty with time on my hands. I'd probably call it "everyone but that sour-faced eejit at number 36" (maybe not)

You didn’t think they would want to join the Facebook group (aka as you didn’t want them in the group). They don’t think you want them to take in their parcels, buy gifts for your DC or chat to them (aka as they don’t want to go this).

So your neighbour is good enough to take in your packages and your bin but not good enough for your fb group? Yes you are very unreasonable

You made a judgement without asking and you were wrong. They were generally friendly neighbours and you didn't invite them on the facebook group. It was up to them whether to join and how much to engage on it, not yours. Go and apologise and explain - they might speak to you again, if you are lucky. Lesson learned: do not pre-judge people (there's a c.2k old warning on this one!).

Apology + flowers + homebaked cookies / something decent from M&S

On an asap basis

You made her decision if to join or not.

Why not her decide?

She probably thinks you have issues with her and has withdrawn her goodwill.

Your claim that they 'keep to themselves' doesn't ring true if they used to chat to you, take in parcels and bins and give presents to neighbours' children. It sounds like you must have excluded them for another reason?

People who don't usually (or never!) join in with community things, still want to receive all the general invites everyone else gets.

Firstly, it keeps them in the loop about what is going on locally. Secondly, their lives may change, e.g. retirement or widowhood, and now they do have the time/inclination. Finally, not being included, suggests they're not welcome. This is hurtful.

I would drop them a card saying very sorry; explaining I assumed they would be much too busy, and didn't want to badger them into joining. (Adding in something flattering about their job's long hours or their devotion to their beautiful garden. Whatever you know is important to them, and will ring as trueful.)

And stressing I would be delighted if they would be part of the Facebook group. Giving them all the details about the Group and providing my email to contact me if they want to be formally added.

They may choose not to reply, but will almost certainly be much less upset. And, think about sending them a nice Christmas card this December. No expensive stamp will be needed!

It's very important everyone can fully relax when at home. So it's probably worth a bit of awkwardness to try to fix this.

Very Good Luck!

Why didn't you ask them to join?

Yeah that was a dick move. Invite her.

Oh come on @hallogalorrr, of course you’re in the wrong to set up a neighbourhood face book… and then selectively choose which neighbours can join!

Dont complain about how she doesn’t want to talk to you… in her eyes, you’ve deliberately left her out, so why would she?

Either go and speak to her and sort it out or don’t. But don’t make out that you haven’t been the person to cause this in the first place!

Well, yes, you deliberately excluded them which has caused ill feeling. And, you needed the internet to tell you this?

Good on that neighbour for refusing to take your parcels, I would never do any good towards you either.
You have created a stupid feud over a pointless Facebook group. How immature.
Your actions actually constitute cyber bullying.
