My two equally favorite smells are puppy breath (because it lasts such a short time and then you have liver or some other nasty breath) and FRESHLY GROUND COFFEE, especially the first pot of the morning when my husband makes it and brings me a cup in bed.
My most enduring beloved smell is my husbands' neck and I also love the way my chin fits perfectly into the little hollow of his collarbone......sigh!
And, you know, all three of my favorite smells are reminiscent of each other.....
