If other people didn't mention Valentine's Day, it would pass by without me noticing. It just doesn't exist for me, whether I'm in a relationship or not.
*I* don't have plans. But someone has plans for me. He's told me them. We'll be going to a particular restaurant. Then we will go dancing till dawn. Then I'll go home with him. Then we'll spend nearly the whole of the next day in bed and order in. Then in the evening he'll walk me to the train station or put me in a cab home.
Did I mention we're not involved? Just one date a few weeks ago and that was it.
I told him it sounds like a great plan, all he needed now was the girl.
