Volunteering at last year's Night at the Tropics. An annual summer soiree benefitting the Aviary. Yay Sundresses!
They say that smell is the sense most closely associated with memory. I would argue that at times music can be a stronger reminder, but the scent thing is definitely true.
Our apartment takes on a certain scent when the air conditioning is on. Not good or bad, just distinctive. I forgot about this until I came home this evening, and as I climbed the stairs was hit in the face with a deluge of memories from last summer.
