Why does Chick resent his mother?

Chick resents his mother's constant presence. She was a hands on mother, always there with a note of encouragement, a lecture, or simple words of advice. She wants him to go to school; Chick wants to play baseball. She reminds him of his manners; Chick doesn't want to hear it. Unfortunately, Chick never realizes during his mother's lifetime that she was simply doing her job.... guiding her son and wishing him the best life he can lead.
