Things I'd like to note:

To be certain is to be sure. To be a curtain, you hang in front of a window so nobody can peek in.
Their stupid. Their stupid what?
I before E except after C. Unless it's weird. Or your neighbor.
Lay down the bed and lie on top of it.
'Lot' is a noun. People seem to forget that a lot.
Can you use the bathroom? Then perhaps you may.
The farther you go, the further you are.
It's wrong to get its abbreviation wrong.
The past has passed.
It was better than that way back then.
You threw it through the window.
Contemplate on whether the weather is spelt that way.
Who's worried whose isn't right?
You're sure your getting it right?
Be sure that I accept nothing except proper word use.

Then again, I didn't even spell Phoenix properly when I made my name. Well, oh well.
