actually, :) and (: are not opposites. They are just reciprocals. Therefore:

:) X (: = 1

:( X ): = 1

1/2 X 2/1 =1

1/4 X 4/1 =1

:) X (: = 1

I think he is trying to say this.
(: is the opposite of ): because happy/sad, you know the drill. But (: is also the opposite of :) because it is a mirror image. Substituting the word happy for a smiley face and the word sad for a frowny face, we get the following logical equations:'

Happy is the opposite of sad.
Happy is the opposite of happy.

Pretty far out huh? Yeah yeah I know what you are thinking, "but that can't possibly be true?!" But if you are still reading this definition then by now you must think I'm pretty smart or at least am on to something, which I'm not. But I can certainly pretend like I am. If the above equations are true than the whole world is turned upside down! Emotions have no identity! What the hell? Holy camoley this is ridiculous what are we going to do the world is falling to shit
(: that's the way uh huh uh huh i like it uh huh uh huh

This is a happy face, if you've never noticed.. See?
People often use this face while socialising by internet or cellphone.
This face is used when people are happy.
(:
Socialiser 1: I am soooo happy ! (:
Socialiser 2: I can tell, you even added a smiley!!
Socialiser 1: Yes, that smiley proves how HAPPY I am (:
Socialiser 1: Gee, that sure makes me happy ! (:
