When we were young We were small but we didn't know it, ah-ah-ah When you were hurt You would smile so you didn't show it, ah-ah-ah And I can't believe you're mine Can't believe you're mine When we were young We were brave, we were wild warriors, ah-ah-ah And you liked to race So we'd run to the distant shores, ah-ah-ah And I can't believe you're mine Can't believe you're mine ♪ When the night came we would both say goodbye and go ♪ But now that I'm older I'm sleepless outside your door So let me in I can't believe you're mine ♪ Now we are tall We are wise We are tired of growing, ah-ah-ah And all of this time You and I How did we not know it, ah-ah-ah And I can't believe you're mine Can't believe you're mine Can't believe you're mine
