Secret from Your Smile

I just found a secret way When I want to make your day I just found a treasure map How to make a happy lap Sun is only in your eye, when you looking at the sky Secret map is in your smile Let me knock and say hello, I can wear something yellow That is only working style (Smile) Show me your secrets from the past (Smile) Show me the future comes fast (Smile) Show me the sign I'm looking for Help me to unlock the door Way goes up into the woods There's one in the neighbourhood Way goes down on the sea
