I would care, but I'm not sure whether I'd stop seeing them because of it.

I'd care for two reasons. First off, smoke smells if one smokes during breaks and similar. It sticks to your cloths, to your hair, everything. And I really, really don't like the smell.

Second, I worry enough as is about being abandoned because my T gets sick/dies. And he's perfectly healthy (he claims). Smoking increases your risk of getting sick so much, I don't think I could deal with it...
