Number 5 or is it 3?

Number 4 arranged for last weekend when we planned to be away so Other Half took a key to the agents and cleaned up.  They cancelled.  Number 5 is coming this evening and the house is not much worse than it was for number 4 so take the knickers off the radiator, pick the socks up off the floor and we will do.  It has been on the market five weeks and there has been about as much activity as son on a Saturday morning.
