When I stay with my daughter and her family I occupy a room that has outside access. I used to go outside to smoke on that porch. What I didn't know was that when I'd leave they'd open up and air out that room for days, and have to wash the curtains and everything. And what I also didn't know was that when they'd visit me they'd have to do all their laundry right away or their house would stink from my smoking. They never told me before.
Valuable feedback to keep the quit.
