My brother-in-law. He smokes at his mom’s house, even though she herself doesn’t smoke. My wife and I both think it’s indescribably rude, but MIL won’t hear of and says that if she doesn’t mind, it doesn’t matter.
You can also sort-of count me. I sometimes vaporize in the house, but 9 times out of 10 Mrs. Homie will send me outside to do it. And what I vaporize isn’t tobacco.
