Fly Away

What makes people so different?

I understand different cultures, different languages, different sexes, and races and personal habits, but what makes brothers and sisters from the same family have such different thoughts and ideals?

I can see a little bit of influence in birth order, or if there is a long number of years between two siblings, but those born one, two, three, four, in a house with the same two parents, eating the same foods, going to most of the same places during their formative years? How do they grow up to be so different?

It has to be that we continue to grow long beyond those so called formative years. So, then my next question is what makes some children need to fly away from the nest while others just crawl up the family tree and build nests on different branches?

I could write books on both these types, but it would still be all speculation, or perhaps just a lot of perceived personal experiences. I wouldn't really know for sure.
