The couple who moved in next door to me ten years ago changed everything in the house bar the roof and the external walls. All the windows,doors, flooring, bathrooms, kitchen, heating, garage cut in half to make a utility room, paving in the drive dug up, replaced then dug up again because she wanted some garden, new paving at the back covered with decking, conservatory dismantled and replaced with a brick structure and the entire garden emptied then covered with gravel and triffid- like succulents. And they were in their sixties. It went on for years. Even the brand new shed had to be turned one quarter round. The only thing not replaced is the low garden fence, so she can lean over and say, are you going to pull up those weeds, and pull the leaves off my bushes because if they come over my fence I can cut them off.
As he is retired and she has never worked and has no friends, they are there All The Time.
