My elderly mum rang me Christmas day to let me know that my dysfunctional sister was visiting her at our original planned time, last minute as is her style. To keep the peace i said okay , how will i know she has gone? She said, i will call you. She still has not although i do know my sister was there for just two hours and its now 2 days later. No apology or consideration and shes done this lots of times before but this time i am angry and hurt but because of her age , do not want to hurt her! A.i,b.u not call her?
