Had a friend in High School that was absolutely brillant! However, I noticed a change in him around10th grade. I was so naive that I thought he was just being funny every day at lunch. My friends knew he was high...I had no clue. Fast forward and he dropped out of college and joined the Army. Was high driving a tank in Europe and rolled it.
Dude had straight A's, barely studied, and blew it all out of his ass for weed. Hope he is doing well. Last I heard, he was still living with his parents, but that was a while ago.
