Well, Flash, you should have warned me that you are writing in Germanic English. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Humility and humiliation are two different things but very close.
Humility is self generated, but once you seek it in others you are humiliating them.
The first one is better described as humbleness, so tell me how humbler can a professor be than to talk to you as a peer and so friendly? <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
The second could be a concoction of embarrassment, degradation and dishonouring.
Telling someone that he /she is acting higher than their status means that you look down on them in humility, which is humiliation.
I am not an idiot pretending to be a professor, but a professor pretending to be an idiot. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
I have a lot of time to spend after my retirement, so please allow me to behave like a fool occasionally. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
There might be some wisdom behind the acts of a jester (“William Shakespeare”)
