When your Spotify playlist is on shuffle and a song that you haven't heard for quite sometime suddenly comes on, unearthing all kinds of emotion and stirring beautiful memories of someone or of a shared moment, but it is something that doesn't make you feel sad or lonely but rather feels like a soothing kind of warmth that makes your eyes glow and lights up your face, brings back all the butterflies that once fluttered your heart but now graces your lips with a smile even when it's time for them to leave again.
