Scott mentioned in another thread that he was adopted, and I was surprised because I didn't remember it coming up before. I was adopted too, so I'm always interested when I find others who were. Uwe mentioned something I also have an interest in and Scott asked a little about my situation, so rather than jack the other thread I thought I'd start a new one.
Scott, I immediately thought of your brother as well. I'm glad you guys weren't split up. Kudos to your mom and dad for taking you both! As for me, My story is (in a nutshell) this:
My parents had six daughters. My mom reached the age (43) where the doc said not to get pregnant again, so they decided to adopt. My parents were very open with me about my being adopted and I mostly avoided any hangups about it. I remember seeing some TV movie as a kid that chronicled the horrible life some kid thought they had because they were adopted and I thought it was the dumbest thing I'd ever seen. My parents were the people who loved and raised me. Who took me to the doctor and dentist all those years and made sure I went to school. Who sat up with me when I was sick and kicked my butt when it needed kicking. I love my parents and miss them every single day since they've been gone.
But, in another instance of life taking such interesting twists and turns, in my 20's I became acquainted with my birth mother, and after that my birth father. That time was actually the one era in my life where my being adopted got a little weird for me. I felt really guilty about having any type of relationship with them at all, because it felt like I was somehow betraying my parents. At the same time, it was amazing seeing my facial features on another person... Luckily, they both were very respectful of my 'space' and let me call all the shots. It took a few years before I worked through that weird feeling and sort of put everything in its place.
I've often been amazed at the similarities I share with my birth parents. That being said, I'm also very much like my parents (my father especially as I get older). That whole nature/nurture thing is something I have first hand experience with!
Like Scott said, it's an interesting life...
