Every year I dread Christmas. Both my parents and my husband's are so demanding and outspoken. They tend to dictate what is going to happen, everything from arrival time to the brand of sherry to be used in the trifle. I bite my tongue and try to please because I don’t want to cause a fight, but I’m fuming inside. I’m afraid a time will come when I erupt. I should say something but I’m not very good at standing up for myself and they are such unreasonable people. Any suggestions?
