Remember that being rude is definitely NOT cool, I mean what do you get out of it? People just think low of you, they might not say it straight to your face, but they won't like you that much. You might think you're popular, but remember that those friends you have might not be true friends.
"Intelligence plus character - that is the goal of true education." ~ Martin Luther King Jr.
A weak person does not know how to be strong, so instead they try to act like they're strong by being rude.
