This morning, when I left my new apartment to head for college, I left my computer on, which I do realize that I shouldn't have done, anyway, this weird guy drove up to the building my apartment was at while I was at the corner, waiting for the transit bus to take me to college. When I came back with a friend of mine a few minutes ago, I found not only was my door unlocked because I remember locking it before I left and my computer was turned off. I want to know that guy was and did he have a key to my room.
