isn't for you

Vince returns to their apartment at about six thirty. He discovers his roommate playing music out loud from an expensive sound system, sitting on the window sill, back facing out.
"Hey." He greets Seth with a nod from the hallway. "Having fun?"
Seth grabs each side of the window frame and leans back, wild grin on his face, and falls backwards. The frame comes loose and he feels empty inside with the wind on his back, a splinter in his left palm and a broken skull.
