I used to take the higher road and try to turn the other cheek but now, I tell everyone just how I feel and what I am thinking. Some people call me hateful but those are the ones who can't say anything nice anyway so I don't worry about them. It is a lot easier for me because then people know exactly where I stand on things. I don't like the feeling of being walked on and that is how I feel when I hold my tongue. Just don't lower yourself to their level. You can be tactful and blunt at the same time.
When at work, because we are dealing with sick, injured and stressed patients, I take it and I laugh out loud in my mind or behind closed doors
