I'm always one for telling the truth. And really, I can't help it---it's projectile. The world needs it no matter how ugly, and let's face it, it's a pretty ugly world.
I'm fascinated, also, how one person can take or handle the truth. I use to be one who would be sensitive but could dish it out. Which by I mean, in my own head I could dish out the truth. Now as I've gotten older, I could care less. This also stems in part, I believe, from being in a management position where I must deal with unreasonable people and employees. The employees are the best at being unreasonable, I have found, especially when dealing with newly graduated teenagers. And they know how to argue and they know how to get their way, much like my 4 yr old.
I say if you can't handle the truth, then put your kryptonite where your mouth is.
