Well, this is what happened an hour ago guys (and gals) I was lying in bed (Yes, at 11:55!), and I can hear the front door open. I didn't know if my housemate had returned, or whether she'd left the foor unlocked and it was a friend of mine coming round Anyway, I hear this rustling downstairs, and I start to panic a bit, so I do the only brave thing I can and hide under the duvet Anyway, for about 4 mins, I can hear him rustling around downstairs (I could tell it was a he), and then he comes upstairs, where peering through the duvet, I can see his legs (getting a bit scared at this point). he wanders around for a minute or so and then leaves. 10 mins later, I get up. Check outside the window and see nothing, and so go downstairs to check the door. It is locked. So this bloke obviously had a key Now, the house is up for sale, and the estate agents have a key, and as far as I know, that's the only other key. So I email my housemate to find out if the estate agents have been authorised to enter the property today (we're not moving out till Jan 31). She rings the estate agents and says that the bloke was a surveyor, and they've known for 3 days that he's coming round, but they've been too busy to tell us!!! So, although it's sorted (however unsatisfactory - and believe me, the agents haven't heard the last of this), I am curious as to what happens next I assume the bloke had a key so that he could enter the property and survey the house whether anyone was in or not. Now he didn't know I was there, and yet he managed to survey the whole house in under 5 mins without even coming into the main bedroom or ensuite bathroom. Now that's an efficient surveyor!
