School Calls!

Eric got a D on his test and is wondering what everyone else got... they all got A's and B's. Then, when Eric gets home, his mom says she got a call from Eric's principal. Eric runs upstairs. He thinks to himself "oh no, she definitely found out about the grade." Then his mom says, "its just about your grades." Eric is so worried until finally he admits his bad grade. His mom is surprised because the principal called to say Eric got straight A's, but she is not mad, as long as it doesn't happen again.
