My friends and I were sat in my front room chatting at about 1am, when the front door handle started to move and a guy poked his face up at the glass in the door. We screamed and he started shouting how he loved us etc through the door. He went away then came back again, at which point we said we'd ring the police if he didn't leave. I live at the top of some steps which are quite a major route out of the town centre, so I do get a lot of drunk people passing by.
Whilst he was obviously just some drunk guy, why do you think he was trying the door handle?
