There is something about smells that can trigger memories instantaneously. I recall seeing someone that I had not seen in many years and the first thing she said to me is "you still smell the same". I was wearing the same perfume I had worn for years but it made me laugh.
We were somewhere the other night and we all trying to figure out the scent. Who else wore that scent?
Just as music is equated with a time of your life, so is scent. The smell of the beach, someone smoking a joint on a bright sunny day walking down the street, sugary smells coming out of a bakery, someone walking by you and their perfume lingers in the air just long enough to trigger a memory.
We are still trying to figure out who wore that perfume but it was a very funny conversation that triggered my senses.
