Remember when the music/came from wooden boxes hung with silver wire....

Nostalgia.

The desire or ability to live joyfully in one's past.

My father wrote a song for me when I was a little girl....

"Little girl you look a mess/you've gotten/jelly stains upon your dress/and peanut butter in your hair/defying laughing standing there"

It goes on, but you get the idea.

There's nothing out there like the love of a parent for a child. Treasure it while you have it.
