What the Tortoise Said to Achilles

So the last two days in the morning me and Damil have been following Emma and Marie-Claire around while they were showing form 2s around the school. Any excuse to get out of class, I didn't even have any classes yesterday because of it. At lunchtime today me and Ryan were trying to jump and sit on unorthodoxly high stacks of chairs (and Amanda (no, the other one)(but without the sitting)) - now my right leg hurts. I don't know if I bashed it on something or if I pulled the muscle. I really want to try to do a backflip but I'm too scared that I'll just fall on my head. I can't seem to find anything soft to use as a landing pad. I think I might try sometime today, off the table outside on the grass. I might indeed.
