Box - Box lyrics

I was with you that night When you opened the box All you've hidden away You said you'd opened it once But you gave me your trust Said you'd throw it away So we had our time Got a new life But you could not keep the box out of sight You opened a box With treasures inside Curious to see You opened a box With all that is made To ruin me You opened a box The blackest of all You should've hidden the key So a year past by And you showed me around In your crowded mind I was starting to see With you the real mystery Is why you don't throw the box away I was there everyday Took a jump, and a turn, and a leap for you But you could not see With the box you're losing me You opened a box With treasures inside Curious to see You opened a box With all that is made To ruin me You opened a box The blackest of all You should've hidden the key You were just too blind to see With the box you're losing me
