I don't know if it's because I'm getting older, or the more obvious answer......because EVERYTHING is scented nowadays.
I find most smells obnoxious. I have never worn perfume, but do like cologne on men. But walking behind some people drives me crazy with the smells of perfume, fabric softener on their clothing etc. I usually cross the aisle to get away from them.
And walking down the laundry detergent aisles! Forget it! My eyes water. I've since made a batch of homemade laundry detergent and I love it!!!! It works great and no smell. I've used vinegar for years for my rinse and love it as well. Don't like perfumes and flowery smells on my clothes.
