LOL, cool! People don’t look very friendly. That would be a problem for me because I’d be trying to talk to people.
Sometimes they're too friendly. Years ago I would ride BART daily to my jobs downtown. Very crowded during rush hours, people bunched up against each other. There were a few times when buxom women would press up to me, chest to chest, and give me big smiles. Very uncomfortable for me as I'm married! Then there were the ones who would pinch my butt. Those were the days when I wore suits and carried a briefcase. As I got older I switched to jeans and a backpack, and the nonsense stopped. Now retired, and since Covid I avoid crowds.
Please do continue talking to people. I've seen good interactions. One time I was concerned when a young black gangster type guy sat down next to an elderly white woman doing knitting of a sweater. But as they talked, they shared hobby information on knitting; turns out the black guy did knitting as a hobby.
