OK, this is quite a lighthearted thread. But I have been away for a week (actually less - 5 days) and since I've come home, our house seems to have regressed to a batchellor pad state
Flooded bathroom,
Stale, damp smell in house
Kitchen not terrible, but some strange smells coming from it and grimy looking.
Boy toys dotted around - i.e. half dismantled bike.
Evidence of having lived on pizza, fried egg sarnies and wine.
'Manly' smell in the bedroom 
DP not home yet ;)
My question is - I now have a fear that my house always smells and looks a bit dirty and I had just grown accustomed to it - or has it reall regressed that badly in 5 days? What do visitors think when they come??
