I was at an event where an older guy (50s married with college kids) was saying stupid flirty things to a young woman entrepreneur about how pretty she was etc. I pulled him aside and said for him to cut that shit out. So not cool. He had no idea what I was talking about. I asked him if his son was pitching me would he want me telling him how hot he looked? He got it, sent me a gift and next day and thanked me. It is never too late to learn.
