Do you, ya you, know the difference?

Me do no the difrunce.

thnk 4 aksin.

btch.

The only grammar mistake I have to consciously avoid while typing is its/it's. "It's" is sort for "it is". "Its" is used to show possession.

I cringe when I see people misuse then/than.

I cringe when people can't differentiate between they're/their/there and you're/your.

Yep. My best subject in school was Grammar... Wait! Not "was", "is"! Yeppers! I am terrible at Math... 1+1=Kaboosh?

I bet THEY'RE other people who are good with THEIR grammar! Huh? Huh... See what I did THERE? Hahaha! Did it again!
Hm... Seems like YOU'RE great with YOUR knowledge for usage, too!

I've never heard of these words and I've been using English since the 15th century. I hate to be a Grammar Viking about it but people don't seem able to correctly use thou, thine, thy, and thee nowadays.

If this carries on, proper usage will die out and the differentiation of possessive cases and the expansiveness of our language will be lost. In a dystopian future, perhaps a foodstuff will be created with bull meat and the chymosination of milk into caseinates and glycomacropeptides on some kind of bready substance and a cat will say it "can haz cheezburger" and everyone will laugh, knowing - all the while - that it's the end of language as we know it!

I bum hus stake, plose. Gum stake! Gum!

I understand when someone accidentally missuses one of these (we're not perfect), but when they do it repeatedly and/or without care...that bugs me.

Yep, I know the difference!
I wished that more people knew this.

This pops up from time to time.

Sadly, they don'tlearn. Then have the nerve to correct other people's use of punctuation and capitalisation, use of British or American English, or typos.

The mind boggles.

Yeah I know the difference but I don't give a damn.

The dumbasses on Instagram spell weird "wired"

Yes. Sometimes I slip up on Your/You're but I often try to correct it if I still have time to edit. I honestly still don't understand at what point Than/then are appropriate to use though. That and Who/whome is a confusing one.

Of course I do. I'll even prove it:
EXAMPLE ONE: Sadie went to Tibet. There, she learned about Tibetan culture. Place: Tibet
EXAMPLE TWO: Kate and Lulu love their dogs. Possessive Noun: Their (Their being Kate and Lulu)
EXAMPLE THREE: The Cats are old. They're 14 and 12. They're being the cats.
EXAMPLE FOUR: That is your book. This indicates that the book belongs to you.
and
EXAMPLE FIVE: You're a human being. You are being the person I'm addressing.

Users are always correcting me, specially for your, you're. :P

This drives me *NUTS* adults should know these rules! but they don't. It's not because they've not been taught, it's that after 18 most stop reading books.

STFU
