anyone ever deal with a teacher hovering over them?

i’m working right now and feeling pretty awkward because there’s another teacher just hovering in the same room… she also keeps yelling at the kids when they’re just chatting (it’s an art class, so it’s not like the kids aren’t allowed to talk) and shoots me looks when i don’t intervene in the kids using the equipment wrong (i don’t exactly know how it’s supposed to work in the first place unfortunately, it would be nice if she would just tell me what to look out for!)

it just feels like i’m being babysat while subbing and it’s so weird lmao
