Frank Sinatra - Be Careful, It’s My Heart

Be careful, its my heart,
Its not my watch youre holding, its my heart.
Its not the note that I sent you that you quickly burn,
Its not a book I lent you that you never return.
Remember, its my heart.
The heart with which so willingly I part
Its yours to take, to keep or break,
But please, before you start,
Be careful, its my heart.
