Ours is a no-smoking house -- except for my study, my man-cave, my sanctum sanctorum, my little sanctuary that has my desk, a nice comfy chair, pleasant lighting, and around a thousand books. Once I picked up the pipe again having my own smoking place indoors was non-negotiable. (Fortunately herself didn't object in the slightest. She did, however, purchase an air purifier for the room ('cause she loves me!).) She even comes in once in a while to have her own bowl.
My kid, on the other hand, is something of a hypochondriac; whenever she comes while I'm in mid-bowl she'll worry about her throat a few minutes later. But she'll brave the smog to give me a hug or sit and read in the comfy chair while I'm working. Once the whole family assembled in my study to watch exhaled plumes of smoke hit a slice of sunshine for their own little laser-light-like show.
I've had visitors in the past, however, who are anti-smoking zealots who don't even want to bring their kids anywhere near my closed door for fear of what even a moment of "second-hand smoke", or the aura of it, will do them. I'm surprised they even came in the house at all, frankly.
I like to smoke outside, too. When it's not below 0 celsius I'll often go outside.
I know how increasingly uncommon it is to smoke inside, so I'm grateful that I can have a place to do it in without compunction.
