I've been wondering. I smoke and I'm 17, yet my mother doesn't mind as long as I don't do it in the house, and she doesn't say anything due to being an ex-smoker. My father totally disagrees with it because my grandmother from his side of the family died from it, yet as long as I'm outside and not in front of him he doesn't mind as much. So my question for this topic is this, "If you had/have kids at my age, would you flip out or just discuss with them your point of view on the matter and tell them in the end it is their choice, and they will suffer the future consequences?".
