~ Your new cat is beautiful!
Gosh, that is a coincidence, when I read your dilemma, I immediately thought about my brother. I agree, it's a tough one when dealing with family, when you genuinely want to understand and to be understood, not agreed with so much, but heard ~ at least heard.
Funny, when I tried to tell my brother about how I felt, we didn't communicate well there either. Hopefully, you and your sister can communicate well in some areas and in others you just go with the flow. Not the best advice maybe, but I find the relationship with my brother rich in other areas, so I've accepted it now. I also know, that if I ever needed him, he'd be there for me and this caring quality about his character ~ well, I'm sure you know what I mean.
I can't help but wonder if they are able to communicate to anyone at all...
then I think maybe its me
~ Don't feel bad, I used to think I was speaking a different language!
