Have they ever addressed why they made a move from Hertfordshire to Nottingham? I think it's sad that the eldest boy started school in September and made new friends and is now having to do the same again in a new school. For a 4 year old that's bound to be daunting.
It's not that they had to move because of jobs, it wouldn't surprise me if they moved due to their house being recognised and people knocking on the door shouting "YES MATE" then walking off.

They have been very quiet with this house so I'm beginning to wonder if it's because of that.
