How rude!

Rudeness is the weak person's imitation of strength.  Eric Hoffer

A person who is weak feels insecure, worthless, unimportant and so they will do and say what they can to insert themselves into the lives of people around them.  Unfortunately they do it in inappropriate ways that are off-putting to people rather than endearing.  Rudeness, overt or subtle, is one of those ways.  Snide remarks meant as "jokes", behavior that is "assertive" but is really just jerky, etc - these are ways in which a weak (hearted) person tries to prove to him/herself that they are strong in character.  Except character strength is not formed nor displayed through rudeness, quite the opposite.
The next time you are tempted to be rude, STOP.  Evaluate your motive behind the rude behavior or words.  What are you trying to tell others through your behavior?  That you are strong in character?  Or weak in heart (i.e. character)?  If you are trying to prove strength then you won't follow through with the rude behavior/words.

Today's quote immediately made me think of this... *grin*
