First thing to avoid: do not automatically assume the smoker or smokers are irresponsible jerks.
As soon as you get that idea into your head and you stick to it (you're the innocent victim, they're the careless perpetrators), you are probably in for a fight. And when you start a fight, you can never be totally sure who’s going to win.
Drop the enemy thinking.
Approach the person in a respectful manner. Or approach a Board member, or the professional manager, in a calm manner. Ask for their help finding a way, some creative method, for getting everybody’s needs met.
Their need for relaxation (in their own home!) in the best way they know how--a nice little smoke now and then--and your need for healthy air and a clean environment in your own home. If you talk about it with them, you'll find a good solution within twenty minutes.
