It started through word of mouth. People ask you to do this as a favor and it really is a job. I found that having children, people assumed that I would be in town more often so they would ask me to watch their house. Also because I love animals and have a dog and two cats, they assumed that it was OK to ask me if they could drop one more pet off while they were out of town, “just for the weekend.” Well it is still a job. So, because I am too nice, I would always say.
