Some of the songs you heard in different phases of your life remain embedded in your heart. The moment you hum or hear it playing memories of that particular period rush in. Fond or sad nostalgia moist your eyes or makes goose pimples all over your body. I think nostalgia acts very powerfully in songs or music beats and tunes. They enact pictures, peoples and fashions vividly in your inner mind screen.
Movies do too, but songs in some of them act as the catalyst.
You idle at your home and feel extremely bored at times hating to be there, questioning yourself on wasting valuable time. But when you go away you desperately want to be there. Things you hated you start remembering fondly and want them to happen again.
Nostalgia is a potent moving force and one of our most cherished assets. When you meet your dear ones after a long long time just sit down with them and go on chatting. That will be an unforgettable moment.
We need nostalgia to love and appreciate life.
