Ya Know What Really Grinds My Gears?

If you're a "Family Guy" fan like me, you'll know that this post's title is stolen from Peter Griffin. Anyway, ya know what really grinds my gears? The incessant misuse of "your" and "there".  It's like fingernails on a chalkboard to me and it makes me wanna put my head through a wall or strangle the offender. Basically, it just makes the person look stupid. Like, did you NOT pay attention in English class? So, let's review, shall we? You should say, "I am your friend" or "You're my friend". And then there's... "They're not there" or "It's none of their business". Gotta love the subtleties of the English language. On second thought, maybe what really grinds my gears is the stupidity of the careless. Sigh.
