I also agree that this wouldn't be ministry as they have any right to come and ask to come in. But I tottally agree with playfelt. and I also wonder that ppl can come in to check the house out to come back to rob it later or something. to try to keep me safe I use facebook and word of mouth for advertising. I don't trust kijiji. And I ALWAYS say the child has to be present to. I send away also to rebook when child is here.
