Tonight I was at a family gathering and observed my daughter in law and her older sister. It was fascinating, yet almost disturbing. They clearly love one another, yet this rivalry thing is ever present. Does it ever go away or at least get better? I know my good friend would very likely in that situation of had told my son had he called with that question "I don't know, call your grandparents or ask your own parents." Maybe siblings react inappropriately when they are feeling insecure...and then they crave that one upsmenship "thing" stemming from childhood. As best as you can, try to let all this go. As you know by now, difficult child's are draining to the core. Their antics can drive you crazy; so simply don't let it drive you crazy. Sorry so simplistic, but sometimes you don't have a choice. Life is too precious and you are too smart and valuable. I too think he is trying to push your buttons. As you also know by now, only those who actually have a difficult child "get" what having a difficult child really is like. Maybe you can do mom and dad's TG every other year!?!? consider a cruise!!!! They are great! This stuff is frustrating. You are human, so you will feel it. Shore yourself up with good self talk, pampering, trips away and by planning ahead.
