Why did school mum do this?

People like this are very inconsistent.

They can turn it on and off at the flick of a switch.

It's awkward for you and up to you if you carry on being polite.

My stance in this situation (probably wrong thinking back), was to give someone a couple of chances, and then completely blank them.

The problem with this of course is, that you become the nasty one.

It's much better to be neutral/polite I think and just go with it.

Thank god those playground days are over.

I had one like that. She recognised me from another context, was friendly for a while and cooled off.

It was blatent when she went into blanking mode. The others in the group would wave and say hello and she'd stride on with her nose in the air deliberately snubbing me and ignoring her friends' actions. It did bother me the first few times but once I realised that it was going to be a pattern, I decided to see the funny side.

Some people are just weird. I make sure I still loudly say a cheery hello as I walk past, even at the ones that don't always respond. It just makes them look like a dick when they don't reply and I feel good for being friendly.

Definitely her, not you. There is someone like this at my child’s school. In reception she seemed really nice, since year 1 sometimes she will say hi, mostly will sneer and blank unless it suits her. She now has a reputation for being a miserable old bag and I take it with a pinch of salt. I have to say I have stooped to her level unfortunately and now don’t bother. But unfortunately her child misses out on loads of play dates and days out because of her behaviour towards other adults. Her child is also morphing into her too and does the same thing if you say good morning. Don’t waste any time thinking about it. It’s year 5 for us now and her behaviour hasn’t changed!

How do you know that she heard you? Surely there’s a chance she was just in her own world and thinking about something?

Sorry, I’d never ignore someone on purpose. If someone says hi, I’d always respond. But I never stand and chat, but then again I wouldn’t do that at parties or at school.
Whoever did that is being a cow.
All I’m offering is the opinion on someone who isn’t there to make friends.
I’d advise to just ignore her now 🤷🏼‍♀️

People are just weird OP. Be thankful you're not her, because she clearly has 'issues'.

I can't tell you how glad I was when my last child left primary school and I could leave all that school gate nonsense behind!

Look, I am one of these mums. Sometimes I can be arsed. More often than not, I can’t, I’m not there to make friends. One child has successfully made it through primary, plenty of play dates, plenty of friends etc. One nearly finished primary and the same. Hasn’t made a dot of difference that I haven’t made time for the parents. I have a fulfilling home, work and social life and have never seen the need to try and make friends at the school gate.

@PsychIsMyFave
I was a bit confused at first tbh, wasn't used to her talking to me so was a bit startled!
I started using a different entrance to the playground to avoid her & sometimes sent dh to collect the kids instead. It was bloody stressful!

A lot of parents at my dd's school were like this, very fake and up themselves. I just said a breezy hi, didnt stop to chat & collected my kids.

One day a snooty mum started talking to me because she found out I was friends with a minor celeb whom I went to school with. Then she was all over me like a rash and I was glad when our kids went to different schools.

This.

I don't buy the "face blind" and "impaired sight" excuses (for the vast majority of people). I've never been blanked at work. Funny how it's only school mums!

They're rude. That's the long and short of it. Up themselves and rude.

Oh I get blanked at school too OP. Lady I've spoken to for hours on a mums night out (voluntarily, she could have chatted with others) has subsequently blanked me. Another mum did it from the get go. She has a few mum friends and presumably the rest of us are surplus. Others are ok but lots are standoffish. So I don't bother anymore, I just do the same back and keep myself to myself. I'm too old and busy for that crap.

Lots of people have poor social skills (and are rude). You just have to not take it personally.

"Seriously messed up"?
Rather hyperbolic, no?

I've found at school , I only get spoken to if there is nobody they'd rather talk to there. I wonder if it's the same in this case.

This is 100 percent on her not you. I've had ot happen to me. Typical narc behaviour. They get a kick out of reeling you in then ignoring you and making you wonder what you've done wrong. You won't be the only one she does it too.

In that case, just rude op.
I can’t think of any other reason someone would overtly ignore someone greeting you using your name directly.
Avoid this kind of drama and this kind of person. Can you be arsed with it?
This is why I used to drop off and piss off.
I wouldn’t know any of the parents of kids in my kids school if I fell over them.

I know one like this, she is nice to me in a group but blank me on my own. She just doesn’t like me but doesn’t want to look like an asshole infront of her friends. Not one off, consistent behaviour. I used to try to say hi to her at the school gate but she would turn away as soon as I spoke and pretend she hadn’t heard me. Really odd.

If you said Hi name how are you and got ignored that is rude. I can’t imagine ever ignoring someone in that circumstance unless I just didn’t hear them.

I am also face blind so just don’t recognise people out if context. If you hadn’t said her name then I would have assumed it was that but saying her name leaves little doubt.
