It is Heart.
My first may be accumulated or spent My second crumbles after disappointment My whole is broken so a note that was sent May be able to reach its recipient
What am I?
My first is near an organ which thinks My second can contain your cold drinks My whole helps you to see between blinks
A part of the body that you can give it whole to somebody you like. But once it is broken, it aches, it’s painful and it throbs. What is it?
