I did grow up "smelling things": my family could identify the owner of an article of clothing left behind at our house simply by smelling it. "Oh, this jacket belongs to that family." Strange, but very practical skill. Even today people's homes carry an identifiable smell that, if I have known them for some time, I recognize. Even if they have moved to a new country, they still smell the same! (But, when I married and we had our own place, my brother pointed out that I no longer smelled like a Busenius, but that we now had our own "Aspegren" smell.)
The smell of nasturtiums always makes me think of crouching over my mom's flower bed as a child, diligently picking orange blossoms. Rice pudding and fresh bread, of my mom. The wet forest smell that comes here in Holsbybrunn always transports me to the hidden jewel of the British Columbia leg of the Trans-Canada Highway, The Enchanted Forest. Without fail that wet forest makes me think, "enchanted forest." The scented skin of a plum or an apple, freshly picked, I associate with my grandfather. Cut grass of summer evenings going to bed too early while my parents finished up the yard work. The first tinges of wood smoke in the air always make me think of Bosnia and El Salvador and cooking fires. Comfort clothing softener instantly reminds of the deliciousness of Martin's smell when we were dating. (He still smells good, for the record, but different.)
I suppose it can be like this for most people, the richness of smell, but it seems we've forgotten how to breathe deeply and slowly. Something about being adults and busy and such, maybe we forget to enjoy breathing.
