Three smells just came to visit me from the past. They are gone now but they were here, I promise you.
The first was the smell of the modeling clay they gave us in kindergarden. The second was the puppy my mother brought home from the SPCA when I was ten. The third was this one particular girl I met at a high school soccer match.
Each one of these smells -- along with its time and place -- exists now only as a memory in my mind. The instant I die they will be gone forever.
In all candor, I should note that I am still in a fog from a bad night's sleep, that my allergy to ragweed is in full swing, and that I've got one hell of a sinus headache going on here.
That was three.
