The Grounding

Sneak around the house and smoke 6 times without getting caught by your mom. The more you smoke, the faster she moves, and she can only move when you are not looking at her. If she gets close enough, she will kill you.

Your mom grounded you. To get back at her, you need to smoke 6 times in the house without getting caught. Be careful though, because if your mom catches you, she kills you.
