I've done basketball for over 30 years. I consider myself semi-retired from it because I have chosen to do mostly JH games. I am really enjoying this year, helping the young kids and coaches. I get satisfaction from knowing I have done a good job and that I am filling a big need. Sometimes I get frustrated at having to deal with such a low level of ability (turnovers, etc.) but I get through the game and realize why I am out there. At the same time, I am helping some rookie officials and that is satisfying too. It's amazing how much we take for granted that young officials don't know.
Although I try to consider each game a "big" game for the kids, I also know that the number one reason that kids play sports at these levels is to have fun (born out by several studies that I have read). Unfortunately, parents and some coaches see winning as the most important thing. You'd be surprised the number of grandparents that attend these games and they seem to be happy simply by seeing their grandkids play.
I've had to deal with wild coaches and disrespectful players but not very often, especially when they see that I won't put up with it. (3 T's this year) I know that the coach that I T'd learned from it because he came up after the game and apologized. Overall, the players and coaches at this level have been really fun to work with.
Everyone has their niche and it may change with time.
