I still remember when my mother accidentally sexually assaulted a 30ish year old guy on the subway. My mother is not a small woman-- a good 5'10 in flats, and not thin. She, and some family, were visiting for the weekend. She thought she was sitting beside my cousin (or so she claims), and in an animated moment of conversation she grabs the meaty part of this young guy in short's upper leg, and gives it a good shake. His look of horror has stayed with me to this day. Poor guy, who was smaller that my mother and any of the men in our group, and was paralyzed and didn't know what to do. The rest of our group eventually froze all agape. My mother simply apologized, and then calmy remover her hand AFTERWARD. She played it cool, but I'm not sure if that guy will ever be the same.
