Need a word to describe this situation:
I'm sitting on a train (i.e. public place) and there's a dude talking way too loudly on his cell phone. I look at the woman across from me and we don't say anything, but it's pretty clear that we're both thinking, "why the heck does this guy have to talk so loud on his phone?"
So, the word I'm looking for describes the moment when you and a total stranger have a moment of non-verbal connection and you both know that you both are thinking the exact same thing.
