BettyBoo, I understand how you feel. I used to have a sister. She was 5 years younger than me and, as children, we loathed each other. Fortunately, that changed as we grew up and, although we were very different, we became close as adults. There's something unique about that bond of shared upbringing and parentage; no matter how close or long-lived a friendship may be, it'll never be the same as a sibling relationship. My sister died in 2001 and I miss her yet. So many little things we used to share: things that would make us laugh, or cry, or angry ... so, yes, I'd also love to have a sister.
