JLM, because women have a much more sensitive sense of smell than men, women are more easily aggravated or disgusted by certain smells than men (unless it's diapers it seems... lol), thus women's obsession with having a 'signature' scent if you will. If you'll notice, women are more likely to breathe in while hugging people, than men are.... smelling a baby or toddler's head, smelling their husbands as they snuggle in. We are simply more tuned to find scents pleasurable than men it seems. Our houses are no exception, since they are essentially a cocoon we build for the people we love.
That makes the air freshener industry an easy solution to creating 'ambiance'. It means one doesn't need to actually clean the carpet, they can simply mask the smell with a preferred one. They don't need to take the garbage out, they can simply spray chemical laden scent around to mask that of the meat wrapping that's gone bad.
Personally, I love to make my home smell good. But, I do it by cleaning, and if I use a scent, it's an essential oil, or citrus oil, not a chemical in a can. I also keep a layer of kitty litter in the bottom of my garbage can. I dust furniture with baking soda for a couple hours on the days that I'm going to vacuum it. Carpets get the same treatment in the couple rooms that I have carpet.
And if I REALLY want my house to smell extra special... I bake. :smile:
