I was adopted after my Big went alum. I consider that I have 2 families bound by me. The family with my first Big and the family with my second Big. With my 1st I was the only Lil. With my 2nd I think there were 2 others so I had twins...I have a Lil and she has 2 GrandBigs a couple of Aunts and so on...
I never felt like I had to give up the other family b/c I was adopted, I was just the only one still active so someone else stepped in. BTW, there were no hard feelings that this was done we were all great friends to begin with, and to prove it both Bigs were in my wedding
