Okay, so there are a few other music GLOs here in our music department. One of them we've been on bad terms with in the past, but the last year or so we got along great, and even did a few socials together.
This year though, they've been mean to us and said crap like we're "snobby little girls" (we aren't), and told us we couldn't hang our banner in the band room until they had a meeting about it. What the hell?! It's a public room!
THey constantly badmouth us when we have been NOTHING but nice to them. So what can we do NOW? Any advice?
