IF CW moved out of the bedroom at the back into the study at the front, then JM could have her bedroom.
But then JM said that he was moving in with his parents and his sister, so where would they go? The only solution would be for the parents to have the bedroom, and JM and his sister would have to sleep in the corridor.
This was a disaster – at least as far as I was concerned. Our two-bedroomed flat was never meant to accommodate seven adults. Meanwhile JM took it all in his stride, casually stirring a huge pot of porridge on the stove in the kitchen.
