Ahh, I like having someone to like, especially when that someone presumably likes me back. Katie said she called him when she couldn't find me and got worried, and that he got worried in turn. Granted, I'm sorry to make him worry, but I'm flattered that he cares enough to be concerned. Katie said he even offered to come over to my place, to see if I had just fallen asleep.
I can't wait for class tomorrow, when I get to sit next to him for a couple hours.
