Isn't it interesting how certain things have a bond with something entirely unrelated, but relevant to you? Such as a song reminding you of a place, a meal reminding you of a person, a smell reminding you of a book you've read; because at that time that smell was present with you whilst reading that book, so when both of those things are in that contemporary moment, you subconsciously bind each of them together to create a connection in your mind which could be of any emotion, e.g. woe or contentment, based on the situation or location, that later on becomes a sweet reminder, or a sad memory. For me, the feeling of warmth, laughter and love, are just some of the reminders that are attached, that will always come back to the thoughts of you.
