Don't you think that this is so out of order?

I had art class the other day and our teacher was ill so we had a supply who is actually meant to be really nice. xD

So my best friend and I went about doing our art classwork, then our supply teacher let the whole class out 15 minutes early. c: But of course we didn't know we were early so we headed down to our next lesson like normal

What we didn't know was that our supply teacher had called the rest of the class back into our art room (realizing her mistake) and so we were left wondering the school wondering with some other people where everyone else was.

Then one of our friends came and told us that we had been let out early and that we had to go back up to our classroom- so we did. xD

When we got back, our supply teacher started having a go at my best friend and I, saying that she talked to us specifically on the stairs saying to come back in the classroom (which she totally didn't). But what I totally don't get is that she only had a go at my best friend and I and not the other three people who were with us?!

All I can say is teachers will be teachers. But yeah. She was mean
