I dislike all my sisters very much, of course for various reasons. lol but they come to visit my mother whom I have been taking care of for years now and act like they are a wonder for her and they treat her like a kid. Drives me nuts. When they do she just nudges me or smacks me in the elbow to be quiet. Any one have suggestions on how to handle them? Years of biting my tongue is wearing thin and I'm running out of patience.
