One Way Out

You made sure that the door was locked, you didn't want to risk getting hurt. You realized that locking the door would only attract attention, the majority of the doors were open so you decided to open the door. You looked around for a hiding place. Only good place was behind the teacher's desk, so you hid there.
You heard fast footsteps, from outside but nobody came inside to check each individual classroom. Your plan had worked. Time passed. A long time passed.
"Where is that kid!" you heard John from far away. You assumed that he was talking about you.
