Hmm, I love it when people drop by and I'm decent. I think I learnt it when the neighborhood was swarming with happy children. Children come and go all day long. So it became no big deal to have someone wander through and stop to chat for 5 or 10 minutes. (Children count as people, you know.)

If I'm not decent, I'm not home. Very simple. And I've always lived places where I could see who was standing at the front door without being noticed, which helps.
