I find it the hardest word to say, rarely say it, but recently a prospective parent came around and I really felt we didn't "click", for the first time I felt I didn't want to enter into a business arrangement with her. I found her quite demanding, she has 3 children and was "telling" me where they needed picking up etc, I just didn't get a good feeling, I felt she was talking to me as if I would be a nanny, and politely said she might be best off looking for a nanny as I definitely couldn't do what she wanted. She complained that nannies were too expensive. After I told her several times I couldn't do what she wanted, she would keep questioning why I couldn't pick x up from school, she then changed her requirements, asking for any time I had available, I told her (honestly) at this point I don't have any space, and sent her away with numbers of other minders I know. She has now since called me back several times wanting "any" space I have, thinking that I only turned her down because I couldn't fit her in. I told her (again honestly) that I have a couple of people on a waiting list, but she has called again today asking what space I may have by January. She obviously liked me and I am the most local minder to her.
I don't really want to keep her hanging, but am looking for a polite way to say I really don't want to do business with her.
Any ideas?
