At least I think it's never.
Ailz was preparing food all day yesterday. This morning there was moving of furniture....
I look round the house with a visitor's eyes and think "Old Curiosity Shop". How do people keep their rooms tidy? Beats me. I think they must be people without interests, hobbies, pets and books. It's amazing what turns up when you move furniture. A grout whitening pen for instance. I tried one of those on the kitchen tiles earlier this year. It was useless.
