Would you drop this friend

This seems to be one of these threads that hasn’t gone the OP’s way so there’ll be continual drip feeds to ‘prove’ she’s right

I think you have placed this friendship further up the ladder than where she has placed it.

I wouldn't "drop" her, but you might need to shift her down a few rungs.

£100 gift voucher is a lot to give to "an old work colleague". Its the amount I would give to close friends or close family.

Nice insult there plus ageism.

So what did you expect your friend to do? Leave her own party to accompany you to a major train station? Force her friend whose plans had changed to actually take you there. You sound completely incompetent and if she texts you asking for your address and you don’t give it to her then that’s on you.

I really hate prissy people that expect to be thanked every two seconds for every little thing. Are you older? This is very common in the elderly age bracket. It is not unusual to be "thanked" as you put it officially a few months after the event. People are busy especially if they have three children. You need to be a little more understanding and patient. It takes time to write numerous thank you notes, especially with numerous interruptions from small children. Get a life really!

In answer to your original question, OP, yes I would. She can get lost.

Lol wtf does that have to do with anything?

My 16 year old can get the tube without back up

So why did you say "nothing since" ? she wanted to send a card!!

Op people are very lax now but maybe she was sending cards on later.. but I agree a quick thank you text. Your gift was lovely.

OP she's waiting for you to send her your address. Maybe she's someone who has beautiful thank you cards that she's been looking forward to send to her guests.

Only after OP wrote to her and only saying she looked forward to the tea, not thanking OP for it. Assuming they've actually had the tea sometime in the last four months, again, rude to not write in after saying she enjoyed it. This isn't just about social graces, it is just entitled behaviour, and not suitably appreciative of the effort/money spent by OP. Even if it wasn't a gift she particularly enjoyed or liked. In any case, this isn't the way I would behave with a friend who'd come to my wedding and given me a generous gift.

I’m not sure what you are expecting people to say? She’s clearly not up to your standard of friend behaviour so why are you asking a bunch of strangers if you should drop her?

you are a grown woman capable of making your own decisions. She’s a peripheral friend at best so just stop making an effort and I’m sure she’d not bother back so there’s really no issue.

perhaps she feels the same about you

But she did thank OP for the gift.

Folks seem to be trying themselves into a pretzel to make this all your fault (a charming MN trait!) - quite simply, it is rude to not acknowledge and thank you for a gift or to change plans in the last minute which would have an impact on you (without acknowledging and checking with in with you). She seems self-absorbed and rude. No need to drop her as a friend but I would scale down the effort I make for this friend, and definitely no more gifts.

I wouldn't have chased her after a week to be honest.

She obviously has a busy home life and maybe figured the acknowledgement / text would suffice as a thank you (even if she didn't use those words!).

I'm with you op and wouldn't bother with her anymore.
Even i can send a text in 2 minutes.
We went to dhs nieces wedding and got a small card a week later thanking us for the gift and our attendance. They were obviously pre printed and weren't personalised but they were thoughtful and sent immediately.
It's sad really that manners aren't valued any more and people don't see why they should bother.

I think as usual OP it comes down to just trying to match other people's energy and have realistic expectations. Just because you invest a lot in a relationship or give an expensive gift it doesn't mean that others will reciprocate.

I’m laughing a bit at ‘followed guidance and instinct’. As if getting to St Albans involved navigating by the stars and crossing fierce rivers.

sorry OP, I’m sure it was a bit scary if you hadn’t prepared any back up plan at all if someone wasn’t with you. I wouldn’t have loved it in a strange city, but that’s what mobiles and uber are for.

Sorry I've just reread this and realised this was on your way HOME? So her party was still going on? Honestly you need to give yourself a shake and stop being so demanding.

Or if it’s really that difficult to navigate jumping on a tube then most adults would think ‘sod this Ill get a cab’

Its hardly race across the world it’s a journey 1000’s do daily

You're making it sound as though the journey across London to St Albans is some kind of a world trek. It's a daily commuting route.
Surely you can read a tube map at 40 years old. Getting to St Pancras is hardly difficult and pretty much every train (apart from the Eurostar) goes to St Albans.

I don't get the train thing at all. Unless the adult was vulnerable in some way I'd expect them to be able to manage a train journey by themselves.

Really ! I know the addresses of all my friends.

Chasing a new bride and mother of three after only a week is crazy. She certainly had her hands full. You don't give a gift to be thanked, you give a gift because you want to give something lovely and see her happy.
And your comment about having to get a train on your own, well, you're a grown up. It really shouldn't be an issue.
It sounds like you expect more from this friendship than she has to give, so probably better for everyone if you let it drift.
