I remember as a kid, when both my parents got off late from work, I went to my dad's office after school. I would sit on a spare computer and play minesweeper until he was done. Both him and the guy he shared the office with smoked and the office was cast in a perpetual blue haze. Got out smelling like I had rolled in an ashtray. No one ever thought anything of it. Dad has quit smoking a long time ago. 🥰
