Sometimes he’s a little bit weird. He just biked from his house to some store (I think) to play the piano at 06:47 am. I don’t know, but stuff like that makes me a little bit worried about him.
He does this all the time. My guess is he likes playing on the baby grande at the university, and he goes early so he can play without feeling rushed by other people wanting to use the piano. (My roommate in college use to do this all the time.) I've seen him go later in the day and have to wait to use the piano. Nothing weird, or anything to be concerned about.
