Okay this really isn't what you were asking for, but I figured i'd just reply so bear with me.
So during our ASC (it's what my school calls a Study Hall) I went down with my friends to the Music Hall (there's a whole separated section of the building for music related classes, and just random practice rooms with a piano and coke machines). During these blocks, my friends and I chill in practice rooms and be as loud as we want whilst getting NO work done. Or we can pull out any various instruments and sing kumbaya.
ANYWHO, today during ASC I decided to die my hair red. My friend had dye with her, but she had to go write an essay in the library and I needed help. I just put a test patch in my hair (it was like a red ooze-y gooey thing that you kept in for however long) and then went about my buisness doing whatever.
The next block I have lunch, and I eat in the Music Hall as well with my friends. At the end of the block I was talking about displacement in Modern Physics to my friend and suddenly...
"WAIT A MINUTE!..."
I still had the dye in my hair. So I washed it out in the band director's sink.
The end.
Sorry, I really wanted to tell that story.
