#8 Never smack your lips, tsk, roll your eyes or show disrespect with jestures.

Doing these things will ensure you get disrespect in return.  These are nothing less than cursing with body language.  I'm sure you're experienced being on the receiving end of some of these gestures at one time or another.  How did this make you feel?  Surely, you wouldn't want to make anyone else feel that way.  Let's make it a habit to watch our own body language better.  I'm guilty of the rolling eye gesture, usually with people I love.  Mostly I do this in my silly attempt to be funny, but really, it's not that  funny in the first place.  I'm going to try hard to nip this one in the bud.  Starting with me...  Good Luck!
