There is a certain student that I have to "talk" to several times every day. Let's call him Alex. He generally a good kid, he is just ALWAYS out of his seat and ALWAYS talking. So, during my day, I say "Alex" about 100 times.
The other day I was taking a little afternoon nap. Through my sleep, I heard Toby barking obnoxiously in the backyard. It finally woke me up...and I sat up and yelled, "ALEX! BE QUIET!"
