One of the moments that I can think of right now:
After work, I was rushing to get into the metro train before its doors closed, and I got in with no problem, but the doors closed on my purse and wouldn't budge. In front of everyone that could see in a crowded train, I started yanking frantically. There was a nice man on the outside of the train who was pushing at it to get it through, and he was laughing nervously. It was an ongoing task of my yanking and his pushing until others watched until the bag slipped through as the doors opened briefly. A few commented, "Oh, what a nice stranger! Many people wouldn't do something like that for another."
It was this no-name purse that I didn't really care for though and only had my mother bought for function for like 2 bucks, lol.
