I'm a life-long non-smoker, but don't have a 'down' on smokers... I've nearly always found that smokers who give up tend to be far less forgiving!

That said, I don't like people smoking in my house!

OLD JOKE ALERT:

You asked if I mind you lighting up a cigarette. The residue of your pleasure is smoke, which fills my hair, eyes, nose and mouth, and makes my clothes smell.

I enjoy a drink. The residue of my pleasure is urine. So how do you feel about me peeing all over you?!
