Very interesting brother sister storys. Walka and WM, sorry to hear of your losses I don't see my family too often but I would miss any of them if they were gone.
I have 2 older sisters who are twins. One is a Professor at a university (PhD in psychology) The other is a manager over a radiology/nuclear medicine department at a hospital in Florida. They are both intelligent, successful professional women. I'm very proud of them.
They are only 18 months older than me. They are both my padding for any bumps in the road. I love them both dearly. When we do get together, we can spend hours talking and laughing. Neither of them have any interest in horses
