For me optimism is two lovers walking into the sunset arm in arm. Or maybe into the sunrise - whatever appeals to you.
When a man and a woman have an overwhelming passion for each other, it seems to me, in spite of such obstacles dividing them as parents or husband, that they belong to each other in the name of Nature, and are lovers by Divine right, in spite of human convention or the laws.
Romantic lovers require from each other at least the facade of reason: We desire to be what romantic love makes us appear in the other's eyes. We want to imagine we are deserving of the love we inspire.
It's impossible to compare two bands. It would be like comparing two lovers.
Lovers have a right to betray you... friends don't.
