He never knew how to take care of others and this situation was a perfect example for it. You are his friend, as much as he can consider someone as his friend, and you just stumbled in his apartment at 1am, totally drunk. Or to be correct you stumbled in and then fall over, so you were on the floor, laying on your stomach. He looked down at you with confusion and a little anger. “What the hell are you doing in my apartment at 1am? And what’s with that clumsiness? Are you drunk?” He was clearly annoyed with the situation, mostly because he didn’t know what to do with you.
