Steve Job must have LOVED his adopted parents..and I will leave it at that...

I consider it bad luck, bad karma not to meet up with your biological parents if they request it.
I would do it for them as much as for me. We all come from somewhere and from someone, this is why we have family trees and why some people spend a lot of time maintaining them. Family tree research is big on the internet.
Steve Jobs refusal to see his bio-father may have redounded on him. Too stuck up to see his biological father, does not look like a winning formula to me
