I'm sorry that you're having MIL problems, Sandy. I'll be praying that she'll be a good girl while she's staying with you. I have problems with my MIL too. She came and stayed with us for a few days during an ice storm and she had lost electiricty and we hadn't. I had a house full of people and my MIL. I found out that there were worse things than being without electricity!!!!!!!!!
