Be Careful, It's My Heart

Be Careful, It's My Heart
music and lyric by Irving Berlin

Sweetheart of mine, I've sent you a Valentine.
Sweetheart of mine, it's more than a Valentine...

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;
It's not the book I lent you that you never returned.

Remember, it's my heart, the heart with which so willingly I part.
It's yours to take to keep or break, but please, before you start,
Be careful, it's my heart...
