Nostalgia is a bittersweet feeling, a feeling that is both happy and sad. It's happy because it's fun to look back on all of the great moments from childhood. It feels nice to see the toys that used to be played with, the stores that used to be visited, and the snacks that used to be enjoyed. It's also kind of sad though because there is that sense of knowing those times are gone forever and things have changed drastically.
