Another of Madiba's great lessons: you can have a vast difference of opinion with someone but that never justifies disrespect.

The way you approach a person will determine how that person treats you...
'People will forget what you said, but they will never forget how you made them feel.

Disagreement, however, is not anger.

It was a difference of opinion,

We can't disrespect people for having a different opinion.

Most of all, differences of opinion are opportunities for learning.
