Scenario: Dad wants Jr. to be a football hero.
Problem is Jr. may not want to participate in football at a young age. No matter what Jr. wants he ends up practicing and "participating" on a team. He is gun shy. Not sure he wants to be part of this contact sport.
Dad is extremely happy Jr. is on the team. Jr. is very apprehensive about playing and getting involved in the body contact necessary.
Because Jr. has a bad experience (Dad "forcing") him to play at a young age he never wants to play again.
Too many kids are forced tp play by an over zealous parent and they never want to play again.
Let Jr. decide what sport he wants to play or not to play. Congratulate him on a job well done and other than that KEEP YOUR MOUTH SHUT!
