Offer her a beer

You offer her a beer and she looks stunned for a moment, then just sights and moves to grab something to eat. She doesn't comment on how you got the beer or where are you doing there, and you feel that she is disappointed and frustrated, not exactly at you, but at men in general and at all kinds of bullshit that women have to tolerate, like a stranger in her own house offering her beer at 1AM.

She grab some food for herself and leave.

You watch her leaving, finish your beer and go to sleep.
