Last week Nolan's chair broke. Which means we had to go BUY a new tool to fix it since the space to get a screw driver was about 1 inch. At any rate, Nolan was terribly upset that his chair was broken, like meltdown upset but was thrilled that I could fix it (and that we had to get a special tool). When I started to fix it he got really upset that he couldn't see what I was doing (I couldn't see it either) but eventually the chair got fixed, thanks to his help, clearly. I think his favorite part of helping was that the tool fits in his pocket.
