It still both amazes me and at the same time breaks my heart how quickly and clearly music, fragrances and photographs can send one back to a certain period of time in the past.
It only takes a few bars of a song or melody to have me immediately fly back to years and experiences ago, to the people I was with then, feelings that lived in me and dreams that I had. Fragrances are very similar and it's sometimes hard to wear or even sense the same one years later just because it keeps throwing back to then and there. And photographs is absolutely clear evidence of how young, naive and happier we were a while or a long time ago.
We're all made of our experiences and memories, aren't we.
