I hate to tell you this but you haven't seen fast until they get into college. You tend to lose track of the days when she isn't around as often and before you know it - it's Christmas Break, In-Season (50 games in the blink of an eye) and then she comes home for Summer. Most of them get a job in the Summer and then it's a quick turnaround back for Fallball.
Daughter moves back in this weekend and she's very excited to be getting her first apartment. She'll be away from home once again this time next week and I'll once again be counting the days to Fallball games. I've learned to manage the sadness by engaging myself in other activities like this silly kickball league my wife has us in
. I like to think of myself as the Babe Ruth of kickball but I don't help my case much when I point where the ball is going and some stinking brat catches it 5 feet behind 1st base and a complete 180 from where I was pointing.
Bottom line, enjoy every single second you can get with her. Put your arms around her often and let her know you are proud of her. Make sure she is prepared to go on her own and let her live her life. There are going to be mistakes throughout the way but trust she knows how to learn from those mistakes and brushes herself off for the next event.
Softball has taught you both a great deal but it never teaches you how to watch her go. You have to feel the pain in order to learn how to heal.
