Lyrics of Somethings just stick in your mind

Why does the sky turn gray every night?
Sun rise again in time
Why do you think of the first girl you had?
Some things just stick in your mind

Why does the rain fall down on the earth?
Why do the clouds keep cryin'?
Why do you sleep curled up like a child?
Some things just stick in your mind

Why when the children grow up and leave
Still remember their nursery rhymes?
Why must there be so much hate in their lives?
Some things just stick in their minds
