Be careful,     it's my heart.

It's not my watch you're holding, it's my heart.

It's not the note I sent you        that you quickly burned.

Be careful,     it's my heart. 
    E5        G5      A5    E5   B5 
The heart with which so willingly I part. 
     G5        G5     G5    E5 
It's yours to take to keep or break, 
    D5       C#5     B5 
But please, before you start, 
   G5    G5 E5 A5  A/5+  D5 
Be careful,      it's my heart.
