I felt like a thief, walking quickly past the people at the door and making my way to the room in the corner. I knew it was near an exit and down a hallway not taken by many. I wanted to fill out the recommendation and get out before anyone saw me.
I got lucky. The class was being taught by someone new, someone I don't know and who doesn't know me. Except for a few kids, I got in and out, unnoticed.
