I know you're a non-smoker, but can you really call yourself a non-smoker if you're breathing in the smoke I'm blowing right in your face. I wouldn't do that to someone who smokes because in my country it's considered rude, but non-smokers annoy me because they often think they're better and cleaner than us smokers and I'll take every opportunity to blow smoke right in your face. I can bet that you secretly enjoy it, and even if you don't, that's even better.
