Grammar exists to clarify arguments. I make arguments, therefore it's in my best interest to use good grammar to make said arguments sound and unambiguous; otherwise, unnecessary confusion arises. Also, I don't try – it comes rather naturally. I don't know, it's just a personal preference that aids in communication, so why not?

Lol, I actually love it and don't take this the wrong way... You could have said Because thats how the hell I like it. XD

Well, you ask a legit question, you get a legit answer lol. That's the kind of guy I am.

Nice guy ;p.
