To except the host to introduce you to the other people there?

[MrCollinsandhisboiledpotatoes]

Today a friend invited me to lunch in a pub garden, we took our kids along as there's a play area in the garden. She mentioned her sister and another friend would be there also with their kids.
Arrived last and friend was there. I said hello to friend and hugged, nodded hello to the other people and sat down.... expected friend to then say "this is so and so and this is so and so, everyone, this is Mr Collins, nice to meet you, nice to meet you too, etc" but she said nothing?
This isn't the first time this has happened either as twice in the last few months I've been to friends houses for small evening gatherings and haven't been introduced to the people I don't know or asked "you know so and so, don't you?"
Are people just not doing this any more? I thought it was good manners and I've always done it as second nature, never even thought about it?

It's so awkward to introduce yourself. To me, anyway!

You just know some socially inept people, op.

I'm always happy to just say "hi, I'm Apollo" and let them introduce themselves.

You have to be more assertive. It happens to me all the time. Just say hi, I am x

It's a pub lunch, introduce yourself.

I’d always introduce someone if they didn’t know the crowd, it’s common decency, a way to open up the group to include them.

It's not great but why didn't you introduce yourself?

As someone who will forget names I can't always introduce people so I dont
sp this is me
you need to just introduce yourself

Yeah I hate that OP. Introductions are polite, and help you to connect with the guests you don't know. It's bloody awkward if you don't get introduced!

This is odd. Just introduce yourself.
id do that same as work meetings with new clients. No biggie

You forget your own sister's name?

If we were living back in the 1950s and before sure but no i have a voice so I use it

That would seem weird and formal to me, I always walk up to people and introduce myself, and expect them to do the same.

I think it’s more common to introduce yourself to others, and they will then say who they are in this sort of scenario if they are the same generation. The only time I’ve been introduced to in a social setting when it been a persons parent(s)

if you were all sitting down together, I’d expect a brief introduction as well.

Your friend should’ve done it but I don’t think it’s a big deal that she didn’t. I’m pretty socially awkward, but if no introductions were made even I’d say hi I’m Betty.

People get nervous, preoccupied, forget who's already met.

A person with good manners would cover for a friend's faux pas in this situation and introduce themselves. Not sit there like a lump and criticise later.

We were sat in pub garden with some friends and this guy came over to speak with them and sat with us for an hour and a bit and I have no idea who he was.

yes I would introduce people but my friends that I have made through DH don’t do this and they have lived in the same village all their lives and pretty much had the same jobs.

I would not introduce myself in this situation but I would at work meeting. I’m finding more and more people don’t introduce themselves though.

She was rude! She didn’t need to make a song and dance about it, but she should have told everyone your name and you theirs. Weird not to, I think. Although, in that situation, you should definitely have them introduced yourself (but I can see how that feels a bit odd after a certain time period). Poor form on her part.

I agree OP. It's nicer when those that are established in a group setting take the lead a bit with those that don't know anyone. It may not take much to make an awkward newcomer to feel able to open up and join in.

Just introduce yourself

I’d expect the host to introduce everyone but equally if they didn’t I’d just say hi and introduce myself

Didn't say I didn't introduce myself, I did, after I realised she wasn't going to.
Didn't sit there like "a lump"
Didn't criticise her. Just came on here to ask if this isn't a thing anymore because it's the third time I've noticed it recently.

I think good hosting is a bit of a dying art these days.

Ive gone along the lines of, "seeings my sister has forgot her manners and forgotten my breasts.are not made of crystal.....Im xxx all said in jest.....

"my breasts are not made of crystal"?
