My mom and I always get a kick out of the people who we'd see in the parking lot at a store lighting up in their car or as they're getting out, smoking the short distance to the store itself, only to throw the cigarette in the trash before going in. Given how expensive cigarettes are, talk about a real waste of money on so many levels. And then there's the people who stand outside in the freezing cold because they HAVE to have that cigarette and can't smoke it indoors.
Cigarette smoke always makes my eyes water and gives me a headache if I'm around it too long. There's a friend whose home I go to sometimes, and she always opens the door and smokes in the doorway so most of it goes outside (that's her own choosing, I don't tell her to do it-it's her place, not mine), but still, what I can smell is...ech. And I do always smell like smoke when I come home. It is indeed a really nasty smell.
