Any shrinks in the house? I have a poser for you;
My brother is ten years older than me, and when he turned eighteen he left for the Army. For a variety of reasons, he has remained out of my life until very recently. So we didn't really grow up together or anything. I often tell people that I was an only child, because for so many years I was. The other thing is that we are both adopted kids. No blood ties whatsoever.
And with all that time apart, and no blood ties, my brother and I turned out almost exactly alike. I know people who grew up with their blood siblings, and everyone turned out vastly different. I still can't figure out why two unrelated people with two different life experiences should turn out the same? We're talking so similar you'd likely think we were fraternal freakin' twins if it weren't for that ten year age gap.
So! Any ideas?
