I hate when people are saying goodbye and we say goodbye but then they don't leave, they keep talking to the other people, perhaps saying goodbye, I don't know. I tune out then because I'm "finished" and "wake up" a couple minutes later and realize the people are still here and I've already said goodbye so what comes next? I almost get embarrassed.

I think to make it work we have to actually decide to be interested in the conversation/other people so we don't wander off. It reminds me of when I would daydream in class; one gets a lot of D's that way.
