sooner or later

i don't understand you have you lost your mind, you've always been a friend of mine, but you're running out of time, cos i see what she is thinking, it's like she's had enough, cos you never took the time to show her love, even when you knew you should, sooner or later you'll learn, sooner or later you'll cry, sooner or later you'll learn, that you can't live a day without her in your life, i can still remeber chasing her around, but the minute that she gave her heart to you, you just threw it on the ground, when the lights have all gone down and the good times disappear, she may not be here when you need her, when you need her,
