We sometimes have missionaries drop by, which in itself I don't mind because I enjoy their visits if they are scheduled.... but sometimes they would drop by at strange times, and if my kids are at school, I'm not usually dressed for the day.

One time this happened, and I knew it was them at the door, and I didn't answer. They knew I was home.... but later that evening after they called to make an appointment, they mentioned that they came by earlier. I didn't want to appear deceptive, (and I like to shock people), I said, "oh, yes, I knew it was you and I didn't answer because I wasn't dressed," and these are young men around 19... lol.... they always called for appointments after that.
