Well no, it started occurring to me in 7th grade (before that I was too young to notice/care), but it would sound weird if I said “after seven years of it”...makes it sound like I dropped out.
Damn, you’re slow. I’d had it by the second month of 1st grade.
I already knew how to read long before I hit school, so I was incredibly bored by most of the classwork, and finished long before most of the others (speed was a specialty of mine). My mom sent me to school with a book to read while I was waiting for the rest of the class to finish, so I wouldn’t get in trouble, and dang, don’t you know I got in trouble for ... reading !!
I hated school after that.
