One last suitcase full of things She's heading to her momma's place in Boston Nothing left for me to say Too late to fix anything with talking Now the best thing in my life Just told me goodbye Guess you don't know what you got until it's walking out the door The one thing that was a sure thing sure ain't anymore What I had ain't coming back the way her wheels are rolling I used to have a good thing going on Now I just got a good thing going I'm the one to blame I guess Counting on too many second chances Tail lights got a funny way Of shedding light on things you take for granted Don't know how I let it happen Guess you don't know what you got until it's walking out the door The one thing that was a sure thing sure ain't anymore What I had ain't coming back the way her wheels are rolling I used to have a good thing going on Now I just got a good thing going There she goes picking up speed I'll be playing back this moment In slow motion My good thing going No you don't know what you got until it's walking out the door The one thing that was a sure thing sure ain't anymore What I had ain't coming back the way her wheels are rolling I used to have a good thing going on Now I just got a good thing going
