Tennis match

My body is still sore from my tennis game two days ago. I played for three hours straight with my partner from the tennis class. Am I getting old or what?! But it sure feels good, cuz I beat my partner again. =D I can't say I am good at tennis, but it has been a significant improvement since the beginning of the semester. I was worrying about her getting too bored at the beginning (it was her second time taking the class, and I was new at tennis). What do you know, maybe if I keep on playing, I might work out some potential here. ^_^
