Try to get into the Elevator

Side elavator is broken and rarely used by anyway. Which is odd considering junitors office is just next by. Luckely for me it's perfect for invalunteer streakers like me.

I run toward the elevator swiftly, press the button and.... i hear someone. Elevator door was opening very slowly, I used all my strenght to pull them open.

I FAILED! Then i fell on the ground on my ass! Now the elevator door is stuck and someone is right behind the corner!? What the hell do i do???
