Interest or delusion -- who knows?

I had a weird experience the other day when I went to an alumni luncheon sponsored by my college. The man on my right started talking to me. His nametag said he graduated in '72 (I graduated in '94). He had a guest with him, a woman, but no wedding ring, and he talked more to me than to her. He kept chatting with me as we waited on line for food. He said he ran an employment agency in the city and gave me his business card, even though I hadn't said anything negative about my job at all, or that I was looking for anything new. Then he looked troubled and said, "Oh wait, my e-mail's not on the card. Let me write it down for you," and he made me get the card back out of my wallet so he could write his e-mail address on it. It's not even a real business address but a Yahoo one. His company is the only one left that doesn't have their own web site, I guess -- strange. When the luncheon ended, as we all left, he said, "I really hope to hear from you" and looked at me so intently! But, he's 22 years older than I am. :O
Of course, I could be totally misinterpreting the whole thing and he was only trying to be friendly and helpful to a fellow alumnus. Maybe I'm just in a mood where I think (or hope) everyone likes me because I haven't kissed anyone in six months.
