Yes there are situations where it's required, it doesn't matter why you're there, but you're stuck there and you have to talk to people you don't know nor want to know because the people you do know and like are who knows where, so what are some things you do?
me I find something that needs to be done (if something needs to be straightened, or cleaned up, anything that will need to be taken care of I will do. so by being busy I don't have stand awkwardly around. And I get told that I'm helpful or whatever. they think I'm being nice, when in reality I just don't want to talk to them.
or I go smoke, (this is one reason why I haven't quit) as long as I have situations like this I'm smoking so I have an excuse to leave for 5-10 minutes
so I need more tips
