Of course you are, you must be crawling the floor with exhaustion. Why not pajamas and cuppa now. The cats will not let you pass out without feeding them, don't you worry :) Sofa, carbs, telly, don't move.

I can imagine the thought of another SW makes you wonder what you did in a previous life, but I got one for my parents and they are flipping brilliant. Dementia is not best tackled by the family.
