They bought the house before christmas, they haven't moved in but spend a couple of hours there every evening and then go, sometimes they stay there at weekends. There are several cars and vans parked on the driveway and down the road, always the same ones. There has been a massive 4x4 the last couple of evenings on the driveway.
The house is only about 10 years old and the lady that lived there before was very clean and tidy so I can't imagine it's so bad they can't move in for 3 months.
It seems a bit dodgy to me, if you see them outside they don't say hello or make eye contact at all.
What do you think they are doing?
