The wall with the door

You walk over to the wall with the door and windows. Hesitating you reach for the door handle.

What if he hasn't left and is waiting to see if you attempt to escape?

Pushing past the thought you reach for the door handle and decided just to test and see if it was locked. Gently you tried the handle.

"Fucking hell..." You cursed out loud. The door was locked from the outside.

Next, you try the windows. The shades drawn over them are peculiar. Instead of hanging shades, they slide down a track and lock at the bottom. You shake them but they hold tight. A whimper escapes your lips.

By sticking your fingers in the side of the shades and prying out, you manage to look down the hallway. Some similar-looking doors lined it. There was a big door at the end that reminded you of the doors of a janitorial closet more than classroom doors.

Suddenly, the lights went out, releasing a scream of fright from you. Your hand goes to your throat, shocked you could have made such a sound.
