At my junior high, occasionally classes would use the library for special projects/events - fairs to show off what we learned, where other classes would come around and see our displays/hear us talk about our topics. We did one of these is eight grade.

After the fair was over, we had to put the library back in order. As part of this, a couch had to be put back where it belonged. So I started scooting said couch back into place. When it was halfway there, my English teacher saw me doing this, decided I couldn't handle it, and made a guy finish the job for me.

I'd been doing fine and could have finished in a matter of seconds.
