I realized that all my expressions in real life can be summed up in online faces. There's only a couple.

Me being happy: =D

Me being depressed or defeated: -_-

Me being gay happy: ^^

Me being silly: =P

Me being sad: =(

Me crying or really upset: T.T

Me Smirking?: =T (don't really know how to describe that emotion)

Me baffled: O.o

And that's it. It's also great for setting up the tone of the sentence too:
Take the standard "The Mystic is a really kool guy".

The Mystic is a really kool guy. =D
The Mystic is a really kool guy. -_-
The Mystic is a really kool guy. ^^
The Mystic is a really kool guy. =P
The Mystic is a really kool guy. =(
The Mystic is a really kool guy. =T
The Mystic is a really kool guy... T.T
The Mystic is a really kool guy?! O.o

Yup, and just from those faces, you can tell my mood and tone. Who said online wasn't a good place to talk? =D... -_-.
