Reply #21: That's a possibility too

The 2 jacketless guys in the group were significantly bigger than the guy offering me his jacket. The jacket might not have fit them. I was also the most significantly cold one. My husband is always much warmer than me. The other guy had cold conditioning when he was in the navy.
It made me think that it might be gender based because my best friend, who knew this guy longer, suggested that it was gender based. On the otherhand, that might have been some strange friendship jealousy on his part (I, your best friend, am not offering you my coat because I respect your feminism unlike this other friend. In reality, I would be just as cold as you are if I gave you my jacket, but I don't want you to think that I am less of a friend to you than the other friend.)
I offer help to people of both genders too. I have been helped by men, but I have also been helped by a fair number of older women too.
