"Alfred found this in your school uniform." Bruce throws the pack of cigarettes on your table aggressively. He can't act rational and like an understanding parent, he can't. "Any explanations?"

You are Bruce's youngest child after Damian that has a normal life instead of a vigilante one. Bruce has always been trying to be decent father; but your normal teenage problems are his enemy. Finding out that you smoke is one of his enemies that he doesn't know how to fight.
