Sis feels, Mom is in her house so, she will rule. No fighting in front of Mom. She is 93, & we all protect and love her, but of course she is 93 and smarter than the three of us. There are never raised voices but even Mom is afraid to upset my sister. She is very good to my Mom, but can be a bit of a bully. I want to confront and challenge my sis but my bro is like a lot of guys, just don't talk about it. I don't know if I even am making sense, but think I can offer some enjoyment in mom's life, just from my personality. I have always been her kid that made her laugh and I want to do that until she is 103. Wish I could say these things to her. This like a terrible burden only she can handle when in fact my bro & I help.
