1. You're listening to Rihanna in your car and you incorporate the sign language for simile into your dance moves ("...shine bright like a diamond...").
2. You're calling parents on a Friday night, after sending home progress reports, just to to tell them how great their kid is.
3. You listen to the chorus of the Owl City song at the end of Wreck-it Ralph and think, "Wow, I should show this to the kids--that's three different sound spellings for long o."
4. Your biggest smile of the week is when the class multiplication average goes from 74 to 82.
5. You can't stop thinking long enough to fall asleep because you're so worried about creating differentiated instruction so that all of your kids reach their big goals and get the education they deserve.
