I wouldnt necessarily call them creepy just weird but anyway.. I was home alone one night, it was around 9pm or so. Anyhow I could hear someone outside the door and as I was walking to the door I could see andhear the mail flap being lifted. I literally jumped and hid behind the wall, the good thing about the flap is that there are two one of the outside and one on the inside. Its hard to lift the inside flap high enough to look around into the apartment rather you can just look down. I did go to the door as soon as it closed and looked out the peep hole but i saw no one. Needless to say when my dad found out he was mad and asked the porters and everyone who worked in the building about it. I still dont know who it was or what they wanted. Another time same appartment. It was late around 2 am or so and I was in bed. I hear someone banging on the door and ringing the doorbell. I get up and go to my brother who is fast asleep and tell him someone is at the door. He opens the door and this completely drunk guy is trying to force his way in. My brother throws him out and he says no no I just need your window. We're like what? He's like I need your window to get to my appt. My brother tells him to go away and closes the door. Quiet for about 5 mins and its starts again. He opens the door and is like WHAT DO YOU WANT. He's like I live next door I need your window to get onto my balcony. (YES, he wanted to jump from our window onto his balcony-which would be quite a jump at that!) we say no, we dont know who you are now leave. He refused to leave so my brother took him downstairs to the porter, who does verify he lives next door with his mother. He rings the mother up and she says he is drunk, and late and ive locked him -kick him out. So that is what he does. I went back to bed and was asleep for about an hour or so before I hear something outside so I get up and go to the window and this guy is trying to climb the tree!!! The next thing I saw was the porter grabbing him off the tree and telling him to leave. It was so bizarre. I never saw him or his mother after that and I assumed they moved shortly after because or new neighbors are a lovely dutch couple.
