Why are weekends just so short?

Well it was fun to get out in the sun and play tennis. Sadly my shoulder still is not any better. I can hit around backhand and forehand fine but I just can't serve without causing a lot of pain. I'm going to work on perfecting the forehand serve. Which shouldn't be too much different than a table tennis serve. I don't think it's against the rules to serve hitting a forehand but I'll have to look it up in the rule book. Because I was a table tennis champion it might not be as big of a disadvantage as I think. I'll have to try it out on my regular tennis partner to see if I get killed serving that way. Bottom line, I guess I should go to a doctor first.
