I haven't been doing much Parkour lately. I would like to get some friends together and just jump on stuff, but there are few people who would be interested in joining me. Generally they would prefer to play soccer or basketball.
But I did some Parkour the other day! When my basketball playing friends got their ball stuck on the roof of a school, they called me up to save the day. So, I went, got their ball, and threw it down to them. But I didn't come down.
Apparently, I will choose Parkour by myself over sports with friends. Its mostly due to a fear of getting injured which sounds stupid, but its true. Parkour is safe to me.
