He came up to the reference desk and asked a question, ostensibly about the microfilm or genealogy or something like that. He didn't present it as a friend coming to see another friend and shoot the breeze; he came as a library patron with a question. I got up, excited, smiling, and trying to hide it from my co-workers, and showed him around the microfiche, babbling about looping the film through the machine and did you know we have the New York Times and Dallas Morning News from all the way back to the 1840s?
He didn't stay long; when my co-worker wasn't looking, he gave me a quick peck on the cheek, and I was slightly aghast that he would do that in public and while I was on shift, but I was elated that he came to see me all the same.
