Input: Text: this happened a couple of months ago.  usually every saturday, i have sparing with a group of kyokushin practitioners.  my martial arts background is varied.  one of the group members brought their girlfriend and i was sparing with her.  she was punching kind of hard, so i used a controlled ba gua zhang sweep on her (helping her down with my arms).  when i was helping her backup, i noticed she had tears running down her cheeks.  i felt pretty bad and apologized, but for the rest of the sparing sessions she would break up during some bouts.

TIFU by making a girl cry.
