i found one quotes from the scented spectres talk that i found delightful.
Smells are surer than sounds or sights
To make your heart-strings crack—
They start those awful voices o’nights
That whisper, “Old man, come back!”
and HERE is a link to an interesting blog about smells. if you are interested. (you should be. nobody gets anywhere without a little curiosity and a healthy thirst for knowledge.)
