I don't know if I'd describe the one I see as humble exactly, but she receives and responds to criticism and anger well. She doesn't get all defensive or go on the attack. She has apologized for some things - not 100% of the time, but I actually see that as a good thing. If she apologized every time I expressed discontent with something she did, it would not seem genuine to me. I refuse to apologize for things if I am not actually sorry myself, so I appreciate the same in others.
