To feel annoyed everytime my friend keeps talking to people I don't know when out in public ?

[JessieZoo]

So every time I'm out with a certain friend, she always bumps into someone she knows and I don't. And I'm just standing there waiting forever, and she always gets annoyed that I've allegedly been rude for asking her to hurrying her up. Am I the rude one or her? She never includes me in the conversations.

It's rude of her not to include you but also you asking her to hurry up. You aren't the centre of the world. Why not join the conversation?

i use to have a "friend" like this (now relegated to grey rock).
the light shined bright one day when she asked to go for a walk dt, she was upset and sharing some of her life stressors. i was a good ear and generally think my input is reasonable....then at a coffee shop she bumped into a couple she knew 30+ years ago.
she spilled her guts to them the exact same as me (think husband ed and spinal cord issues leading to double incontinence).

it was then clear as light my friendship was NOT so special.
add in a few more events and i ended the friendship (which really wasn't a friendship at all).

Yeah that'd annoy me too, especially the suggestion that I'd been rude when she was the one leaving me on the sidelines for ages.

Sounds like there is a bit of rudeness on both sides.
Does she not say "This is JessieZoo" and "This is passing friend, from work {or wherever}" ?

You are being extremely rude to ask her to hurry up though.
Why not just join in the chat ?

I'd say something, like aren't you going to introduce us? Or introduce myself and join the conversation.

I think you were both rude.

Say you need the loo urgently and she'll wrap it up

I think you were both rude.

It's pretty difficult to join in a conversation when you're not included (explicitly said in the OP) and don't even know one of the people. Friend should be keeping it reasonably short.

It seems a bit weird to linger in deep convo with someone you know casually who you bumped into, in favour of the friend you chose to see who is standing right there! I guess she is very chatty? I'd make it lighthearted, like say "c'mon chatterbox, I'm starving/ we'll be late for x' as if it's nobody's fault really but hers but the friend she's speaking to should take it in a funny way.
