If you live with a smoker, or are close friends with one: don't be a NAG about their smoking habit! (You can make noise about their smoking in the house or near you, because their second hand smoke hurts you – but don't nag them to quit. There's a BIG difference!)
Just three times a year you can ask your loved one – briefly – VERY briefly – to please quit smoking -- in VERY loving and warm tones. (Try surrounding your request with HONEST complements, keep it BRIEF, and they might be more open to hearing you.
But if you speak up more than three times per YEAR, then you're a yukky, obnoxious NAG. Ick! And your beloved smoker will be so ANGRY with you that they'll keep smoking just to spite you. You'll be defeating your very purpose.
I ask nonsmokers to honor their smoking loved ones, and treat them like adults.
And if your loved ones are nagging you, don't fall into the old trap of hurting yourself by continuing to smoke out of your anger toward them. Instead, let them know how you feel.
