Nostalgia is listening to that music that you’ve not heard for ages. Music that once struck a strange chord on your teenage heart’s pages. Nostalgia is watching those pictures in which you smiled with a full set of teeth. Then you laugh, mouth wide-opened, but you’re just able to show your hidden molars a bit. It is picking up a pen at the age of 80 and writing about your first love. It is when a writer rereads his work of decades ago, and it all seems… It is laugh accompanied by tears. Tears of joy from a fountain. A fountain of past and present emotions’ collision! Nostalgia is reading this piece in the next fifty years.
