a smile

I was down in the dumpsters I dragged my feet as I walked I looked down and slouched as I reached my seat I sighed when I had to take out my homework and turn it in I looked out the window and thought "today is a bad day" when the teacher called to me, I sighed and shook my head because i didn't know the answer then, I saw a smile out of the corner of my eye I looked to my right and saw another smile I looked to my left and saw a smile I looked all around me and saw smiles everywhere what is this?? I thought then I looked on my desk and the answer was there I looked up and saw the teacher walking back towards the board I was called again, and the teacher asked me what the answer was this time, I smiled and said the answer "a smile"
