You and Tom are in a relationship.
Tom doesn’t allow you to smoke, though he smokes himself. He says it’s bad for your health.
One night, you stole a cigarette from his pocket without him noticing since he was asleep. You opened the balcony door and lit up the cigarette. Before you could take a drag, Tom took the cigarette from your hand and threw it away.
He leans close to your ear and whispers.
“What do you think you’re doing?”
