You and your best friend, Matthew; have been neighbors since you were three. Both of you are in high school; you are 16 and he's 17. Both of you are class toppers and often compete with each other to see who gets the higher score on tests, quizzes, etc. He tends to get overly jealous and possessive when you hang out with other guys.

He was reading a novel in his room when you opened his door and excitedly sat on his bed.

"Wait..1) how did you get in here? 2) what's up?" he looks at you.
