∆lice escaped

Apparently, as you were walking to class. You passed ∆lices door. You stopped and stared at it for a few seconds before walking again. Somewhere in math class, you ask the teacher if you can go to the bathroom. You didn't really had to but whatever gets you to skip class. I mean, math is boring. Who wouldn't want to skip? You chilled in one of the stalls until there was an announcement from our lovely principal Miss Grace. "Attention all students and teachers. Stay in your classrooms and lock the doors. ∆lice escaped". Uh oh. You stood on the toilet seat praying. Then, you hear footsteps. That was ∆lice's footsteps. Although, you were lucky cause she walked past the bathroom to go to the classrooms. When the footsteps grew quieter, you Practically ran to the exits. I mean, who wouldn't? As you reached the door handle and tried to open it. It was locked. Who on earth locks the exits? As you were about to flee you heard footsteps coming towards you. Yikes.. it was ∆lice.
