Whatever.

Think about this simple expression, which has become one of
the most common colloquialisms of our age. It has become the
creed of a whole generation. Well, what does that word means?
It means....

1) I don't care.

2) Leave me alone.

3) I can't be bothered.

4) I am indifferent.

5) Do whatever u want.

The worst is, when u say that word, you are a really bad listener.

Think about this, why do we have 2 ears and a mouth?
