This is of very little importance, but I thought I'd share. I live in a shared 4 bedroom town home. The management introduced me to my only roommate and the other 2 bedrooms are still empty. Each bedroom door has its own lock on it, in addition to the front and back door locks for the apartment. Normally I trust my roommate and never lock my bedroom door. Here is where this gets a bit creepy. I got home from work and my bedroom door was locked. The management says they have no work orders for my house and as far as they know nobody came in. The lock is a deadbolt, you can lock yourself in or lock yourself out with a key. If I didnt lock my door this morning.... how did it get locked from the outside?
