He smiled as she talked, trying to envisage a life led in that fashion. He could never do that kind of a job - he could never make that kind of a promise to anyone. He was Military, and his job now was the same 230-odd years ago; beneath the fanciful sugarcoating and colourful dressing was the bare fact that he existed to kill people. Be it for security, liberty, freedom - it didn't matter. He didn't give people hope, he didn't give people homes, he didn't even give people joy. He killed people.
But he killed people so that those like Lady Liberty could live in peace. So that those who lived in this country could do the kind of job she did, and give others hope, happiness, freedom and love.
Perhaps a part of him would always be envious of that.
