Most of the time I think they would be shy about it unless you know them well. A while ago my sister had a fight with a girl I liked but my sister and I don't really get along that well, so she wouldn't have told me anything about it and not many people were there to see it also, to ask about it. When I next saw the other girl I asked her about it and she was a bit suspicious at first why I was asking, but I managed to get her to talk about it, and she seemed to enjoy talking about it, probably because she won haha.
