Years ago, my son asked about playing baseball.

I explained the details to him, about missing fishing time, visits to his Grandmother's house (we lived in a different state), bible school, camping, etc. All the things we normally did spring/summer that we would not be able to do with him playing baseball.

Once he learned what he would have to give up in order to play baseball, he decided the other stuff was more fun and important to him. Said he could still play during PE at school.

I never regretted that talk.
