I was, and no, I don't really care to. Nothing against her, I'm sure she is a lovely woman. But, maybe because my family has never made me feel like an outsider, I've never felt the urge to find another family to belong to. I get the feeling that this is rare, though, and that most other adoptees feel differently.
For what it's worth, though, my biological brother contacted me awhile back, and I was willing to talk to him. Although, I disagree with the poster above who said that genetics are important and part of who you are. Blood isn't anything compared to actual love. I didn't mind being contacted by my brother, but I don't consider him family, and we are nothing alike. I am much more proud of my real family, ie, the one that raised me. Anyway, if you did contact her... it might be weird for her, but I don't think she'd resent it.
