Kill them with kindness, unless they disrespect me by questioning or insult me publicly. At that point I will still politely, privately, ask them if what I heard is true, listen to what they say, and let them know I don't want to have drama with them. Then I ask if its ok if we talk turkey, and get things into the open. I would want them to know that they may have misjudged me, but at least at the end of the "talk" they should know where and what I will tolerate. I would rather not judge other people until I hear things from the "horses mouth". That's all I expect, I will not let other people's feelings about me determine how I react to situations, Unless I am in the wrong. Then I will apologize if I have insulted anyone unintentionally. NOt make excuses for my actions. I own my actions.
try ignoring them politely and when that doesnt work i tell them to go away. and if that doesnt work i glare at them and say "hey, guess what. I DON'T LIKE YOU"
I try not to be mean.. to their face ;D
