I stop at the intersection, waiting for the walk sign.  A girl is standing next to me.  She's quite attractive.  Maybe I should...
"Excuse me," I say, "which way are you going?"
She turns to look at me, a bit surprised.  "I'm just going to the bus stop down here," she says.
"May I walk with you?"
She nods.
We get to talking.  Lauren is her name.  Before we get to the bus stop, I've got her number and a coffee date for tomorrow.
The date goes wonderfully. We share a lot of the same interests, and don't live too far apart.  We have a second date set up, this one for dinner.
Over the next several months, we become more and more involved.  After half a year, I realize just how deeply I'm in love.  We've moved in together.  At our one-year anniversary, I pop the question.  She says yes.
The wedding...
I snap out of my reverie.  The walk sign turned on.  If I'm going to ask, I have to do it now.
"Excuse me," I say, "which way are you going?"
She turns to look at me, a bit annoyed.  "None of your business," she says.
I blush.  "Sorry."  We go in opposite directions after crossing the street.
