one off!

Three kit cars roared up to a café I was eating at. Different colours, different exhaust notes, yet seemingly the same type of "kit" albeit variant in design. The 3 drivers, all middle aged males, climbed out and looked different, dressed differently and had 3 different accents, but all humans.
Vive la difference.
So on the face of things we are all humans all almost 8 billion of us, yet we are uniquely made, we develop as individuals and each of us has a different fingerprint and DNA. 
Vive la difference
So why do we insist on our view, our opinion, our way being the best or only one. I say
Vive la difference.
