Skysue, I once had an interview on a Friday and the people said they wanted to start on the Monday. Stupidly, I said they could just bring the contract and money on the Monday as they were starting right away. In the meantime, I announced to all the parents that we would have a new little friend joining us (via email). Sunday evening I get an email saying that the mom has decided to stay home! I later saw this same child and his sister with two different caregivers around the neighbourhood. I think I dodged a bullet!
