My parents trust me now but...

Since you have a conscience and if you want trust, I would stop smoking. Trust is huge, I know! If you want long-lasting trust quit while you have the chance, because all shit breaks loose if you get caught again. After that you can't achieve the same trust you ever had. It will become watered-down plus you have to build it all up again. This is me trying to talk to my 15 year old self.
