I prefer the bona fide, but why? Would I know the difference if I was blindfolded and led into two random, air-differentiated rooms.
I think yes! The former reminds me of walking into a deep freeze, artificial chill, wearing sweaters in the summer. The latter has more moisture in it and therefore more texture. Because it comes in from the outside, it is fragrant and humming with low-level insect buzz. I could tell the difference in a minute ... I think.
But this morning I don't have to. The windows are open, the air is cool and the blue skies shimmer with promise.
