I tend to concentrate first on being hygienic. If a visitor expresses an intention to arrive tomorrow, the first thing I do after getting off the phone or reading the email is head to the bathroom and pick up the Bathroom spray and attack the bath, toilet and sink. I try to get rid of uneaten food as quickly as possible. However, there can be books and papers all over the floor. I try to pick up as I go along, but the messes just returns. I really have to blitz the place if I'm expecting anyone. Unfortunately from time to time, my landlady needs to come round, and asks if she can use her key to enter and I'm thinking to myself " " I can of course tell her to wait until tomorrow, but as she doesn't need me to be in and she was going to come whilst I'm at work, she'd wonder what I was trying to hide. That said, there are far worse places, especially I'd say in some student digs!
