Going back to School

It is time for me to go back to school.

Earlier today, when I picked up Ster from daycare to go to tutoring, Ster was quite cranky.  I kept asking him what was wrong and each time he answered "Nothing!"  I asked if he felt sick, if something happened at school or day care, or just what was wrong with him.

After about 5 "What's wrong?" questions out of my mouth, Ster says, "You need to go back to school because you don't know what NOTHING means!"
