Cheer leading

I  really really really really really really really really REALLY want to become a cheer leader. Lots of my friends are cheer leaders and it looks so much fun. I think I would be able to do it as I am a gymnast and can already do the tricks. The only thing I don't know how to do is stunts (which I could learn) The problem is its super expensive ($95 a MONTH) Another reason is my dad sais its stupid high school cheer stuff that he doesn't want me to do. He said and I quote "cheer isn't a sport. wouldn't you rather be in the sport instead of cheering for it." I know its terrible how could he say such a thing. I tried to explain to him that its competitive then he just said "oh great so now you have to go to competitions" my mum seemed fine with it, if I had a way to get there So for now I have to stick to gym. Next year will be a good time though so cheer you haven't seen the last of me
