Is there a security officer you can call to check it out. Tell them there is someone hanging out by your door and it's making you uncomfortable.

Call the cops

I would chuck a pot at the door.

So open the door and see who is there! simple.

Yep.

So its my day off (i've got the flu) and im laying in bed on the mac.

I live in a block of flats. You have the main security door, then some stairs - another door that you open and you come to 2 front doors. My flat and the one completely opposite.

Im chilling here feeling sorry for myself and someone opens my letter box twice.

Now im not expecting anyone??

At the moment im pretending im not in haha.

Fast forward half an hour and they open it again.

Now im home alone - im supposed to be in work today but rung in due to me being sick.

My boyfriend that i share my flat with is at work and he cant answer his phone due to him being the general manager and will be busy running the restaurant that he works for.

As i said theres another door when you come straight out of my front door - then you have the stairs.

Whoever is trying to get my attention i think is quietly waiting outside my door as i haven't heard the other doors open or close yet.

It's been an hour now
