Singular lyrics

Could you imagine waking up one day And realizing that the world is gone Yesterday it seemed so worthless yet But now its gone Could you imagine waking up one day And everyone you loved is gone Yesterday you didn't care bout them But now they're gone And you're alone A simple smile the light of your eyes Could be missed more than you know Take what you have a single breath Should be singular to me Did you ever watch the sun go down Did you wonder why your friends stay with you You wouldn't miss it till its over once Just like i do an i miss you
