Unfortunately the older they get the worse they get, old dog and new tricks and that. I remember one Christmas lunch where my sister playfully let it slip that I was courting a mixed race girl and the reaction from my Nan was, never bring her to meet her, the races should never mix and her stating she was going to reassess leaving me anything in her will if such actions 'persisted'amongst other things. She also killed a swan with a rock cake but that's a different story
