The other day we had a house viewer coming and, as the estate agents prefer us to be out during that time, we decided to ride round an area where we would like to move. OH duly locked the inner and outer doors and off we went but when we came back we couldn't unlock the inner door. Having strangely lost the key to our back door we got a new lock but OH didn't put it on his keyring, and for some reason he'd also taken my inner door key off my keyring and left it inside the house. Ok we thought. Our next door neighbours have a copy which they use when we're away so they can feed our cats so OH went to their house only to find their key is on their keyring and they were currently in Stranraer. We had to ring the estate agents up and had to sit in the car until they came.
