I'd be so mad. I was annoyed when I found out Abby had seen Lion King in her kindergarten classroom (I know it's Disney, but some of those scenes are pretty intense for a 5-year-old).
Dude.
I wasn't mad, just mildly annoyed. I also would have preferred that they find something active for the kids to do during recess time instead of them just watching movies when they couldn't go outside, so that may have had something to do with it. They spent their entire winter recess time inside watching movies.
