I Do Not Trust Sport Trainers

There is a twinge in my left knee, right on the inside of the kneecap, under the bone. I’ll jump, sometimes. Tendons stretching, stretching, stretching— muscles flexing. My foot leave the ground (pointed, of course). My other leg is straight already (pointed, of course). I lock myself in this position, finding the stretch, the burn, for a second in which I do not know the ground. I fall. Land on one toe, then a foot, then a weight that cannot possibly belong to me. My knee twinges. I ignore it. I stretch the other side, there is no twinge. I go back to my left. Twinge. Twinge. I ignore it. Wearing knee braces on top of leggings, is embarrassing, anyway.
