"I love you, now get out of here!"

That's how Tammie Schrader sent her 7th grade science students to their next class after the bell rang on the first day of school. And every day after that was the same.

After about 3 weeks, she missed the first part: "Okay, kids, get out of here!" She was gently nudged by her students who didn't stand up from their seats. "Mrs. Schrader, you forgot to start with 'I love you.'"
