How will you react?

I think i need to walk out and find a new place, because it's useless if they didn't talk to me or do the 1st move talk to them ;)

I will try to join the convo but if I feel like theyre doing that intentionally, I would need to "pee" I guess.

If I can relate to their discussion, and if I know some or all of them, then I will try to join the conversation. If I do not know them nor be able to contribute anything in their discussion, then I think I will start fiddling on my phone for a few minutes. After that, I will move on and find someone I can mingle with. I am not really a very outgoing person, but I think I can get by socially. For the most part, I only go in parties or gatherings where I know some people. If not, but I need and can attend, I usually leave after mingling a little bit and giving my respects and gratitude to the host/hostes.

I would probably try to join in the conversation. Otherwise I'd just sit quietly.

It really depends on the context. If I am with my best friends and I am not interacting as much then they should not forcefully need to talk to me because they will soon realise that I am sitting silently and there's something wrong with me.

I try to stay there and make myself busy with my phone

If I think they don't want my company I will just keep quiet and do myLot.

Well I have to stay away from them for I don't want to eave dropping.
