An observation about odors and vent hoods
So the phone was ringing, the washer needed filling, the DW was running, and the stock veg were sitting on the counter waiting to be washed. Whap, Whap, there go the onions into the pot. Should turn on the hood. But it's so nice an quiet. Start the heat after the pot is full! Get called away. Laundry to shuffle, phones to answer, etc.
Two quartered onions, cold out of the fridge, juicy, but not particularly tear inducing, in an 11" tall pot, cold on the stove, can be smelled 25 feet and two doorways away.
Life is very different with a good range hood. When it's turned on.
