I always try to be an honest person. I don't believe in lying to people, even "little white lies." I tell people who are close to me "If you don't want to hear my honest opinion, don't ask me the question." And I expect that same level of honesty from the people in my life. If I ask you a question, don't give me the polite answer, the answer you think I want to hear, or a noncommittal answer....just tell me the TRUTH.
At the same time, I don't necessarily believe in brutal honesty. Being honest should never be the same as being cruel. If more people were honest, and not cruel about it, I think the world would be a better place.
