Tiny Little Firefly

I feel like I'm trapped in a jar, like a tiny little firefly. Remove the lid, let me fly with the wind.
The lid is still on and my glow can't hold on for long. I lost my light, but I still fight. Finally the jar is open, but I can't break free, I try, but my life is over. Catch another firefly and watch it die. I know you live to take tiny little fireflies lives. But you can't catch another, you filled the jar with sweet jam, you never catch tiny little fireflies again.
