I came into work this morning, and my cleaning person told me to go into one of the classrooms. The desks--plastic--looked like they had been sanded down. We figured that no one could possibly have done that, and I went to email the sub that was in for the ed director.
It turns out that the teachers (grown women in their 40s) had tried to used nail polish remover to get some stickers off the desks. That, of course, melted the tops off the desks. So, to make it better, they called someone up, and had them come in and sand the melted tops off.
