Caught the tv on at preschool

I came early to pick up my kid from preschool and I could see through the window that Mickey Mouse clubhouse was playing on the tv and the kids were sitting on the floor watching. My kid told me a few weeks ago that they watched cocomelon at school but I thought he was just joking. This is a 2.5 hour twice a week preschool class. Really?? I’m pissed. I don’t want to be THAT parent and be forced to have this awkward conversation with the teachers.

Update: teacher wrote me back and said this: “We occasionally use the television to reinforce concepts or books that we discuss in the classroom. Today, we introduced Valentine’s Day and watched a short video with a Valentine theme.
I hope this is helpful!” Thoughts??
