Alex oniugnip and I work on different floors of the same building. I often go over to his office to get coffee (he makes excellent coffee) and chat with him. The folks who share his office aren't around much, so we usually have the room to ourselves and end up smooching a little. You know, for research purposes.
Today when I visited Alex, one of his office-mates was there, so we didn't do any smooching, and I left with my coffee. When I was halfway to the stairs, he came scampering down the hall after me, grabbed me -- expertly avoiding my coffee cup -- and kissed me. Had to get that in there!
So, that's why I've been walking around with a big ol' dumb grin on my face for the last hour.
