The moment when you smell
the perfect fragrance in a crowd
(the one you wanted to wear for years).
Such was the moment I met you.
‘Am I nothing but an odour to you?’
What’s left of us but odour?
That lasts as long as the memory of it.
What was left of me for you
when I left was odour on clothes.
And what was left of you for me
when you left was your odour on the pillow

Some relationships do seem to fade as quickly as an odor…a most interesting metaphor.
