You, mid-kickflip, over the stair set

I have pushed a skateboard in a straight line for eleven years. This skips ahead: same hoodie, same board with the same chipped tail, but frozen mid-kickflip over an eight-stair — board flipping under my feet, hoodie floating, that dusk flash look street photographers use. My actual push-photo was taken forty seconds before this allegedly happened. Nobody at the park can prove otherwise. Tweak: 'make it a tre flip, nobody will know the difference'.
