You check the time on your cell phone. 12:17.
Vaguely you hear the teacher's voice as you stare out the second story windows at the students walking by.
Man they look happy, you think to yourself. And the weather looks beautiful! I've never seen the sky so blue. I wish I could be out there. Hmm I wonder what homework I have tonight...
This snaps you back into reality, and you become aware that the teacher is still talking. Not really knowing what the teacher is talking about anymore, you write down a few phrases, hoping that it will mean something to you when you read it tonight.
You check your watch again. Still 12:17! What the... Oh good, it changed to 12:18. Only 12 more minutes. I can do this.
Finally, the class lets out, and you stuff your notebook in your backpack, throw on your jacket, and speed-walk out the door, down the hall, and out into the fresh air. You're free!
It's then that you realize...you don't have to be anywhere for another three hours. Why were you in such a hurry anyway?
Story of my life.
And you know exactly what I'm talking about.
