My Choices are Limited

What do I do? I want to play some tennis today. Unfortunately, it's just too cold to play outside. I'm trapped inside. Either on my way to play in a bubble, or sitting in my living room holding a tennis racket. My choices are limited. Sitting in my living room's cheaper than playing in a bubble, but it's not very much fun. Why does playing tennis inside, here in New York City, have to be so expensive? I sit on my couch holding my racket. I'm saving a few bucks, but I'm not really enjoying myself. I wish it would get warm so I could play tennis outdoors.
