why musical theatre is hated by its own people

ok so believe it or not but im in theatre (crew). now im not those kinds of theatre kids that skip down the halls singing at the top of their lungs, mainly because I have some self respect and two bc I can't sing. but that's not why im writing this. there's this girl in my theatre, lets call her Beth. (like Macbeth lol) Beth isn't pretty. now im not wanting to be a hater....but when someone acts like Beth, they kinda pushed it upon themselves. 

im a bi man, i have a boyfriend who is also in theatre and one of the main characters in our show. Beth is very touching with both him and I. my bf has asked her to stop touching him and so have I. how did she respond? she got mad and ignored us for like a week, which is something you can't do with me bc im the head of props so communication is kinda important here. Beth also has like 3 props max but acts like she's the main character (she's no where close) and needs me to act like she's the fucking president, girl. chill. I have 5 others I have to run props to before I even think about you, you aren't the shit, but holy hell do you smell like it. Beth is one of those girls who thinks everyone wants them and that they are too good for anyone....listen. I love confidence and everyone defo needs to have some. but when you're built like the old lady from Matilda im gonna have to ask you to push the bar to the floor. she can't even walk up the stairs without breathing like her lungs just were stabbed, she smells like BO and will get mad at anyone who points it out. along with cat hair all over her body and you can smell it. doesn't brush her teeth and you can see all the shit on her tongue. 

in my theatre there's kinda two groups (this is going to sound mean but its true and im sorry) there's th cool kids who throw and go to parties, and there's the actual theatre kids. Beth doesn't fit with either but tries to be the "cool kids". the only party that ive been at and Beth was also there was our last years cast party. she was the biggest bum ever. I stepped outside to go light up with some friends and some others. Beth came out and flexed that she smoked w33d with her dad all the time. but when the puff can to her, she just glared at it and asked why we were forcing her to take a hit... IM SORRY???????? YOU JUST FLEXED THAT YOUR FATHER IS YOUR PLUG AND HOW MUCH OF A STONER YOU ARE BUT NOW WE ARE FORCING IT ON YOU??????? so what did I do? (in my crossfaded state so it kinda came out) I told her that if she's going to be a downer and ruin every one elses high then leave. of course she got offered and walked out into "her room" at our friend joshes house (not his real name). Beth was sleeping over at joshes house, so she was sleeping in the guest room but made everyone know it was her room and no one was allowed in. spoiler. two straight dude found out something new about themselves in Beths room that night. and there was LOTS of evidence. I could make a whole other post on alll the stuff Beth has done, and lemme tell you its a lot
