How can I get my mum to quit smoking?

that's so unhealthy! since when did your mom start to smoke? talk to your dad about it.maybe ha can help. after all they're couples. but if it's up to no good,try shouting your mom at the top of your lungs to quit smoking(i know it's wrong for their children to do that but its the only way to stop your mom before she'll have a heart disease!) but if she still smokes then say this: "MOM,CAN YOU PLEASE STOP SMOKING ONCE FOR A WHILE!! IM TIRED OF SHOUTING,YOU KNOW! IF YOU REALLY CANT STOP, THEN ILL PACK MY BAGS AND LEAVE!! ILL NOT COME BACK UNTIL YOU STOP SMOKING!! ...FOR GOOD...." there. how about that?hope it works?:))
