Stalker Substitute?

Okay guys, today was a pretty crazy day, but the most significant event was math class. My teacher had a sub ( idek what her name is XD ) and she hated me from the start. She was too lazy to find the test I needed so I ended up reading and then she got super mad and was making me do boring stuff I already did. Eventually I needed to leave her company and stop writing swear words on the whiteboard I was working on while she wasn't looking :3 So I went into the bathroom. In my school there are 4 student bathrooms, 2 upstairs and 2 downstairs. Math class is downstairs so it makes sense to go to the downstairs bathroom, right? Exactly, so that would be where she would look for me, I thought, so I went to the upstairs bathroom and stayed there for twenty minutes. When I came back, she was on me in an instant.
" WHERE HAVE YOU BEEN?!?"
"In the bathroom.."
"I LOOKED IN THE BATHROOM AND YOU WERENT THERE" (wtf  stalker just why)
" I was in the upstairs bathroom" ( idiot )
"WHY"
"Because I like it better" ( my friends were listening to the conversation and they started laughing)
"OH, BUT NEXT TIME ASK MY PERMISSION BEFORE LEAVING THE ROOM" ( wtf no)
Then she left and I was able to slightly enjoy math class more, even though she still hovered over me more then the other students but that look on her face was totally worth it.
This is my brothers story about the stalker sub;
So one of the obnoxious 4th grade boys was swinging his trapper around by the strap and hit my brother with it and then my brother shoved him lightly and then the kid got really mad and started chasing my brother and eventually stopped chasing him and started crying and then the sun came over and was like what's the matter and then the kid was like oh there's my car gotta go and the sub said no you're not going until this is settled and then the kid was like get away from me and then the sub grabbed him and held on to him and the kids mom came over and got super mad at the sub
Haha sucker. I wish you never come back :)
