the idea of live and let live is ridiculous. if one of your loved ones is doing something that worries you or scares you, you're not going to be able to just ignore it and live for yourself. no one has ever done that. "oh, is jeff shooting heroine into his penis again? good for him. dinner in ten." never. humans worry about people. having a relative who is going senile sucks, but it's probably pretty sweet for them. forgetting all your worst memories as you coast through a smooth transition into the great beyond - senility is nature's anesthetic, but it makes everyone else sad so the senile person can't possibly be happy. "she doesn't remember anyone. she forgets things. she has no recollection of grandpa passing. it's just so sad! how can she be happy? we were hoping she would struggle along for years and years, coherent and aware while her body slowly disintegrated around her minute by minute." next time grandma forgets your name, maybe instead of choking back tears, try congratulating her with a high five.
