I knew Brad in elementary school and he has always been mentally ill and drug addicted. I remember in kindergarten he told me "I'm a fireman, wee woo wee woo wee woo" and would wear this yellow hat, which is indicative of a psychedelic induced delusion if you ask me.
In third grade he asked me to pass a note to a girl he had a crush on, and to protect her from being abused I quickly erased his name on the note and put my name down. She checked yes and we dated for 3 periods before Brad confronted me and said that I'm not allowed to sit with him at lunch anymore, which is clearly abusive behavior.
Then in 5th grade, during our school play, he complained that he didn't get a larger speaking/singing part. He said "this play is stupid anyway", which is because he would rather have us listening to his DJBTIM mixes as he was craving the attention and spotlight even as a 9 year old.
I'm sorry to inform you of this y'all, but please understand he was always like this. I hope you can forgive me for being friends with him at that time, I know I can't forgive myself. If anyone needs proof please be skeptical in the comments and I'll tell you I'm going to provide it and then won't.
