So I relocated for a teaching job about 3 weeks ago. Neighbor that lives above me in the apt building was nice and introduced himself. However, now he's getting a little weird for me. Walked in from teaching Friday night, 5 minutes after I walked into my apt there was a knock on the door. Was on the phone and didn't answer. He kept on knocking...so I got off the phone and answered. He wanted to invite me to hang out with himself, his friends, and his daughter on Sunday and watch the football game. Then Sunday I was out running errands (partly to avoid him), got back, unloaded my car, and was putting stuff away when there was a knock at the door. Literally I had just walked in. So he knocked a total of 3 or 4 times before giving up and and going away. I refuse to answer my door, but I should not be bothered every time I walk into the building. I'm afraid he's gonna start running down the stairs and I won't have time to get into apt to avoid him. ADVICE PLEASE!!
