He asked me for my favorites.
How do I choose? It's not a matter of favorite or not favorite... for me it's more a matter of the memory. There are smells that I don't care for at all but that trigger wonderful memories.... Case in point: cigar smoke reminds me of my father.
The human sense of smell is extremely powerful. Some of the most intense memories can be triggered by a mere whiff. (Don't ask about the time Avram sidled up to some lady in an elevator with a big grin on his face and said to her, "Pardon me, but you smell like my dead Aunt"). Sometimes a smell can induce a feeling that we cannot explain, but that must be linked to some long forgotten happening.
I love the smell of freesias. Roses are a pretty close second, but I don't care for lilies, though lilies, along with the smell of baby powder, remind me of my father in law.
I have a bit of a thing for some mens' colognes (good job guys in research and development!)
The smell after a rainstorm reminds me of summers in my childhood when I'd go out hunting earthworms.
Now why we need the smell of Ginko berries is beyond me.....I'd be interested in hearing other people's scent triggers and perhaps sharing a forgotten memory ;)
