<human>: This didn't happen today but it happened a few years ago.

I first started smoking pot in 9th grade, and found some of my mother's pot. Rolled it into a joint, smoked half and put it out (saving it for after school the next day). Before 1st period the next day I used the school restroom and noticed a funny smell. The person in the handicapped stall next to me was crinkling a plastic bag that filled the bathroom with the smell of pot. Not thinking any more about it I left and continued my day. During 3rd period (TV Production) we were filming a video and I was in the trashcan for part of it. Two campus advisers beckoned me towards them. I thought I was in trouble for fucking with the trashcans. Turns out they searched me assuming I was smoking pot in the bathroom before 1st period. The first thing I did was pull out a half smoked joint in a bag out of my pocket. I even showed them the person who was doing the act, and after bringing him in, they found nothing on him. I was suspended for 2 weeks (btw the 2 weeks followed directly into spring break which I was grounded for the entirety of). My mother made me deliver news papers with her at 3 in the morning every single night, weekends too, for three weeks. All this because someone lit up and not me.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Someone smoked in the bathroom and I was blamed for it cause I coinsidentally had a half smoked joint in my pocket.
