Speaking of Teaching English...

Here is your grammar lesson of the day, friends:

A LOT is two words
CANNOT is ONE word

"it's" means "it is" (It's hot outside.)
"its" is possessive (Put the towel on its hook.)

"you're" means "you are" (You're a sexy muffin.)
"your" is possessive (Your hair makes you a sexy muffin.)

"they're" means "they are" (They're going to go to the mall.)
"there" is a place (Put that over there.)
"their" is possessive (Give them back their volley ball.)

That is all for today - go forth and use great grammar!
