I know that if I didn't call the school if my kids were out, the school would call me. As a matter of fact, they scared the heck out of me once when they called to say that my daughter wasn't there, considering I had put her on the bus that morning. Turned out that the teacher forgot that she had let her go to the bathroom right before taking attendance. Although it scared me half to death, I was glad they were that on top of it.
