I used to yell at my son when he played football and basketball.
“81 who told you you could play?”
“81, you have been disowned by your family”.
“81, wake up!”
“22, play some defense.”
“22 you will have to get a ride home”, when an hour before I told him I won’t want to be seen with him after the game if he continued to play half assed.
You know what? He plans to treat his kid the same way.
If a boo crushed his sensitive spirit I would be ashamed of him. He knows he has to do something to earn cheers and he earns boos when he does something to deserve them.
