Yes, it's always interesting to me to see what happens when I'm in an elevator with other people. Will they stare straight ahead and silently ignore the other people in there with them? Will they smile and nod or say hello? Will they play with their phone or talk on it, or chat with their friend and share their conversation with the others whether they want to hear it or not?
One difference I noted after moving from NYC was people here are more likely to nod and smile or just say hello than stare straight ahead, which was more the norm in NYC.
But I like your suggestions for jury-pool room behavior, good thnking, @Dyna-X! +1
I must say, the stare straight ahead was also found in Northern NJ, and it is extremely helpful on the opposite coast when coo coo nellies decide to engage one in a bizarre conversation. It only takes minutes for them to realize they do not exist in annieland.
