it feels like that unexpected hint of perfume that has lingered for too long. your breath catches, you feel it. underlying all those other things - the smell of warm bodies and cooled off coffee, fresh ink in the printer and a glue stick, leather and new book, sweaty smells of the day drawing to an end - and you smell that perfume you put on so long ago. then that is all you can smell.
the blues feel like that. all pervading, unyielding, unwilling to let go.
