I do as well Mike. No doubt your parents are quite proud to see their siblings so close. I told Sofia, you both will have the best friend in the world for the rest of your life if you cherish each other. I will explain the same to him when he is older.
That is something I never bothered with when I was younger, so it is difficult these days to keep up with my siblings. I was much older than most of them. Thank you for your thoughts.
