Frees?

I have no idea how the concept of free periods came into existance. I mean, I'm just spending all of this morning in the academic center because I have no classes all this time. It's boring! I have all this free time and nothing to do with it. I made a new banner celebrating the season finale of my favorite show, Avatar: The last airbender.- And with my luck I'm spotted by a teacher and kicked out. I have to end this with a simple 'good bye'.
Well, Good Bye
