Forgiveness or at least _tolerance_ is a very important social
tool. It allots you degrees of freedom that you might not
otherwise have.
It's a tricky thing when overused the wrong way though, as
people can often see through it.. .especially if it's the kind
of transgression people _trained_ to see abuse of
forgiveness/tolerance... like authorities and such.
Think about the labels we allow to be applied to ourselves.
I accept the label of "Nerd". I'm not guilty for it, nor am I
sorry. I accept it because of the immense degrees of freedom it
provides me; to be an "absent-minded professor", to have
obsessive hobbies... to be late to things... to overexplain
something.
