Honesty is very important although I often tell mistruths to avoid hurting peoples feelings, which is part of being tactful. I don't know - maybe it is just the military in me.
I could tolerate being around a dishonest person, an intolerant person, and a person with no tact, but someone with no sense of humor and I would just not get along. Especially since I'm severely sarcastic.

Honesty, it's the best policy xD
