I think you're fucking stupid(Spelling lesson!)

I find it simply astonishing that 10th graders fail to spell the simplest of words. These are things I understood by the time I was in fifth grade. So here is what I would like to tell all of facebook because everyone's shitty spelling is getting under my skin. I must say, I am blessed to have smart friends who can spell correctly.

You're is a contraction for you are.
Example sentence: You're a fucking idiot.

Your shows possession.
Example sentence: Your shitty spelling makes me sick.

Too can mean two different things.
Too can mean also.
Example sentence: My friend's ex boyfriend sucked at spelling too.
It can also mean to an excessive degree.
Example sentence: It's too bad you're such an idiot.

To is a preposition.
Example sentence: I advise you to go to the store and buy a fucking dictionary 'cause every time you text/chat me I am reminded of what a total fucking moron you are.

Two is a number.
Example sentence: My two year old cousin can spell better than you.

There represents a place.
Example sentence: There is a dictionary on the shelf, I suggest you use it.

Their is possessive.
Example sentence: That is their dictionary however, I won't tell them if you take it because you clearly need it more than they do.

They're is a contraction for they are.
Example sentence: They're horrified by your stupidity.

Its shows ownership.
Example sentence: The child did its spelling homework, UNLIKE SOMEONE I KNOW.

It's is a contraction for it is.
Example sentence: It's a shame you're so stupid.

The apostrophe is used to show possession.
Example sentence: Those are Obama's turbans.
or The girls' books were on the table. The apostrophe goes after the "s" because girls is plural.
The children's ball was in the street. The apostrophe goes before the "s" because children is already plural.

I know eleventh graders who can't make words plural so I figure I'll add this in here too.

AN APOSTROPHE NEVER MAKES IT PLURAL.
It's not dumb-ass's , it's dumb-asses.
Example sentence: You are a bunch of dumb-asses.
Example sentence #2: It's that dumb-ass's decision.

Than is used to compare two things.
Example sentence: Obviously, I am significantly smarter than you.

Then is different(I'm not sure how to explain it).
Example sentence: I considered dating you but then I realized you were a total fucking idiot.

What's the difference between they and thay?
They: They is used to refer to two or more people
Thay: Thay is not a word. Perhaps you were trying to spell "they"?

Question time. Does it drive you insane when people make spelling errors and use the wrong there their and they're? If you haven't noticed, I'm a total grammar/spelling nazi.
