Even though it has been many many years (grade 2) since I was taught the difference between your and you're, for some reason this lesson has always stuck with me. It's like nails on a chalkboard to me when people mess it up.

You + are = you're
Stay tuned for tomorrows lesson on the differences between "There, their, and they're".
