I was not a coach in any sense of the word, but I would take son to hitting facility and feed balls into the machine. I don't miss that because no matter how much net we put around me, he always got something through at least once.
He and I did most of the travel together, whether it was the five-minute trip to the HS until he got his license or the six hour trip to colleges and beyond. We had a lot of serious conversations, and lots of meaningless listening to music, talking about school, etc. I think it helped form a terrific lifetime relationship.
We still have a great time talking baseball and other sports now, but it's the same great time I have hearing my daughter's stories of her work as a dietitian. Raising a kid is an amazing gift, it just evolves as time goes by.
