Trapped in a Box: Mime Basics

"This is the classic. Wherever I go, all the kids want to see me trapped in a box. Here we go. We start off with a normal expression. We're moving forward and there's a wall. I've got to do my just regular wall. I go to push on it, and then I'm a little confused. Then I say no problem, I'm going to go this way. I reach out. What? There's a wall there too. Now, watch that action. Look at my arms extending and bending. Now I've got one wall, two wall. No problem. Out this way. Now I have to build this expression from this wall, to that wall, to the third. I'm almost trapped."
