As I was coming home from work yesterday, I passed by two men in my apartment building. The first was waiting for the elevator, which I didn’t want to ride with a strange man. The other was coming out of the stairwell as I was going in. I held the door for him and he said “thanks” and tried to make eye contact. They both said “hi” to me as I passed, but I said nothing, looked straight down at the floor, and did not turn to look at them or smile, something I would have done before Tuesday.
