night as a metaphor for life

Sitting outside, around 1AM, just coming from a light-filled room, my eyes need time to adjust to the darkness. I find that night is in a way a metaphor for life. You're young and naive--cannot see things that are obviously there--and then as you grow older, your eyes adjust and you're able to see more. Nothing happened to the darkness or to what the darkness concealed--the change occurred within your eyes.
