Thoughts About Jamie

I've been living away from home for the first time this year and have found myself thinking a lot about Jamie. We're in some of the same classes, but I never see him outside school. It's funny because I barely talk to him when we are around each other; mostly just nod and smile. Yet somehow, my mind is constantly replaying every little interaction with him. Why does this happen? Am I lonely or just infatuated? Either way, it’s a bit of an odd realization.
