PD,
Two things- My son is still on a "need to know" basis. If I don't call and ask, I probably get a call with a recap of the season (maybe).
Money wise, the young one has a debit card with my name on it. He never has to call and ask for money, it's just my bank calling telling me I need to put more money in there.
Ken, to be honest, I don't ever recall a parent yelling at the coach, the umpire or the opposing team once last year.
