I can easily answer, “Music.”
Music definitely brings me back to the feeling when the memory was created.
Music is the strongest to lock everything – ambiance, feelings, thoughts, experience.
Like now, I am listening to MØ – Final Song. Suddenly the moment where I was cuddling and made him laugh, caught me and now I am smiling. Haha, I loooove his laughter, and moreover, I am the reason behind it.
Guess I can’t live without music. It is way too precious! 🙂
