Mrs JtH moved in gradually;
Slippers, first, (I had a spare toothbrush for her use), then....
Favourite 'going out' coat,
Push-bike,
VCR,
Stereo record/radio player,
Cat......................
It was at this point she stopped going back to her house and shortly after put it on the market........
Apart from putting things in the wrong drawers and cupboards in the Kitchen, (which she still bl00dy, does, btw) she fitted into my routine pretty well...........and we still muddle along together almost 20 years later.
