When the teacher is asleep...

Have you looked inside Willy's desk?

There's a block of wood and a crayon.

Maybe you can write with them?

In fact, you can write a hall pass for yourself.

The white crayon makes the pass look more official.  Use it.

But you'll get sent to the bathroom.  You are going to have to get past
Spider if you want a chance to get through to the front door.

Spider is going to demand something from you, as long as you are polite
to him in your responses.

You have a Nintari at home to keep you occupied.
