Get a little room fan and crack a window open?
It's your wife, not a co-worker or a buddy-pal, so the difference in opinion can be harder to sway. Instead of trying to reverse the way she thinks about the vape cloud haze (and
please believe that I know all about confrontations with a wife over this), do something about the thing she's complaining about and it'll go much further than sitting her down for a powerpoint presentation and a lecture.
A desk fan and cracking the window open
didn't eliminate the cloud haze that she hated. There's still a low hanging haze at the end of the night, it's not much smaller than it was when it was an "issue." It did, however, show her that I was taking her opinion about it (i.e. 'I don't like this haze he's producing') and doing something about it.
...
or... she's just given up on it. I mean, a notch in the win column is a notch in the win column, I guess.
Pepper in some stats and sources about how it's not a poisonous cancer fog ("here babe, I'll text you a link to some study that was done, made me more comfortable about it, check it out").
Something something 4d-chess something something...
Good luck
