..your heart, I promised you, but when I got it, what did I do

 I broke it,

didn't mean to, but I did.

2nd verse (repeat the chords above)

 ...I didn't mean to, but I did..

Refrain

I wish that I could take back,

the morning scented nights.

and all the tears you shed for me, 'cause I thought I was right..

Now I give up all my life for the second time, please tell me.

Chorus

What the heck did I do?

I wish I had a time machine

Undo the things I didn't mean.

Oh, how do I apologize to you

I wish I had a time machine

I don't wanna lose you.

Repeat the chords on the verse.

Then refrain and chorus.

Turn back time, turn back time

Turn back time, turn back
