You're Wondering about the age-thing

I'm sure many of you noticed that in the first post, I referred to knowing my sister a lot less time than she's been alive (although the percentage is going up as time passes, I suppose). I didn't want this to be a stumbling block, but also didn't want the explanation to interfere too much with the previous post.

My sister is mine in spirit and truth, but not by blood or the law. 8 years ago we met through our roommate. That is, the roommate and I were her "foster parents". Over the years she (the sister, not the roommate) has been absorbed into my family. She is sister to my brother. She is Aunt to my nephew. She has been embarrassed by our parents, though mostly she's in love with the idea, if not a little guarded against them, as she is most people.

Legally, she still has a mother, well, that whole mess takes some time to tell. For now, let's just stick with this brief aside.
