Analysis of On Giving

Those who dare give nothing
Are left with less than nothing;
Dear heart, you give me everything,
Which leaves you more than everything-
Though those who dare give nothing
Might judge it left you less than nothing.

Giving you everything,
I too, who once had nothing,
Am left with more than everything
As gifts for those with nothing
Who need, if not our everything,
At least a loving something.
