A Friend should be radical

A Friend should be radical,
They should love you
when you're unlovable,
Hug you when you're unhuggable,
And bear with you
when you're unbearable.

A Friend should be fanatical;
They should cheer
when the whole world boos,
Dance when you get good news,
And cry when you cry too.

But most of all,
A friend should be mathematical,
They should multiply the joy,
Divide the sorrow,
Subtract the past,
And add to tomorrow,
Calculate the need
deep in your heart,
And always be bigger
than the sum of all their parts.
