There will be no discussion about the fractal nature of bark. Jonathan is baiting me here, trying to get me to go off about the recursive nature of leaf growth, which was his 7th-grade science project. I no longer care. The one thing I do still carry around resentfully from that whole event is that his project finished fourth, mostly because the judges - including the school secretary - didn't understand his project. The girl who did a really nice vinegar and baking soda volcano finished ahead of him. It's one of my prime examples of how schools favor girls shamelessly.
Or maybe I have taken the bait after all, and that episode was what Jonathan was trying to draw me into, so I would say nice things about how brilliant he is, er, was.
