But it's a small miracle if you remember in the morning

WHY IS IT that when you are taking someone home from a bar, conversation gets awkward as soon as you walk out onto the street? You could have been chatting the person up for hours, playing the game, saying the cute things you say, testing the waters, stepping in and stepping back, and then the moment the two of you step out onto the sidewalk, this happens:

"So... my place is this way."
"Okay."
Silence. Walking.
"So... what's your last name?"

Which, of course, is probably something you should have known already.
