One of my friends gently told me today that somewhere in my blog, I used it's when I should have used its.
It's is used as a contraction for it is or sometimes it has. For example, It's hard to imagine I used it's incorrectly.
It's should never, ever be used when it is possessive. For example, One time I snuck up on a groundhog and it bared its teeth and made a noise like someone violently shaking a jar full of marbles. I swear.
So naturally, I'm mortified. But it gets worse. I can't find it. I use it's a lot, a really lot. So I challenge you. Save me further humiliation. Find it and bring it to me. Alive. I'll make it worth your while. I'm not sure how yet. I'll let you know when you find it. If it even exists.
