A guy in my math class asked me "didn't you go to ________ school? I said that I did and that I graduated in 2015. And then I heard him quietly say, "2015." He's always staring at me but today he seemed nervous. Maybe it was because we had a test today but I don't know. Anyways, any ideas why? Like I said, we never met in high school but I knew a few of his friends.
