Sibling

Sometimes I wonder, how my brother and I could be so distinctly different?
We have same parents, same backgrounds, lived in same flats and apartments; yet our thoughts and behavior do not resemble or jive.
I know for a fact that we perceive our past dissimilarly.
I know whom I have come to develop into through experiences.
I see whom my brother has come to develop into through his.
I am certain that my childhood has a brutal impact on my outlook on life.
I don't know how he views the life events we have been through together - respectively - as children.
And I don't think I will ever find out.
Fact is, I believe most likely I will feel better not knowing.
