Just because she skates doesn't mean she has to compete. Skating is still an expensive sport if you count private lessons and skates/blades and such. But competing makes it much more expensive with the choreography and costumes and fees. My fiance gets very very grumpy if he doesn't skateboard on a regular basis. So he just goes out to a local skatepark and practices his tricks for a few hours every day when the weather permits. When he was young he thought he was invincible and got himself pretty hurt a few times, but now he's older and knows his limits. No rail tricks, obviously. But the physical activity and camaraderie with his skateboarding friends relaxes him. "Sports" can just be really any activity, it doesn't have to be structured if you either don't have the funds for it or if that's not what makes her happy.
