I have royally jacked my shoulder working the past week with a rotatory cuff injury, because I needed to pay my rent and couldn't afford time off work. I'm going to need to take 1 - 3 weeks off work for it to heal correctly.

He's the type of dude that'll force you to get in his car after school because he doesn't want to sit in the parking lot alone, overall he's a pretty chill dude he's fun to talk to and has a huge pee pee.
