I've seen it happen to a coach I know! It was the last inning of the game, his team was down by one, two outs, bases loaded, his kid (7 years old) was hitting with two strikes on her. And then he hit her with the pitch for strike 3. His little girl was crying, his wife was not happy, it was not a good day for him.
Been there, done THAT!! My DD (6yrs old at the time) didn't cry, she just started yelling at me all the way from the batters box to the dugout in front of everyone. Oh, they ALL thought it was HILARIOUS!!
As soon as it left my hand...I thought.... Ahhh $#^%! Doinked her right in the hip. She tried to swing at it but..... yeah...well it wasn't funny at the time. lol
