Substitute

 I am sitting in someone else's chair, at someone else's desk, in someone else's classroom. In 4 minutes, her 3rd graders will come back from gym and I will teach them compound sentences with her slides and her lesson plans. 

In front of me on my desk - her desk - is my green travel mug of coffee from this morning. In the bottom of this cup, there are only a few drips of cold, stale coffee I made at home 7 hours ago. Still, in these last 4 minutes of my prep - HER prep - I repeatedly raise this cup to my lips, letting the bitter drops fall into my mouth. 

And in these last few minutes, I scribble in my notebook. I scribble about how my 12 year old daughter is writing 50,000 words this month and I can't. I write about diagramming sentences. And as I grasp at the last few bitter drops of creativity  still in my brain, I realize that none of that can substitute for making something that's mine.
