love is all you need?

Assuming the love we feel is love, not need (because if I could be arsed, next in this lecture series is a discussion on the fine line that exists between the two), loving someone and expecting a return on our emotional investment, doesn't mean our love isn't unconditional.

Maybe the expectation is of an appreciation of our love, or maybe we expect our love to be reciprocated. Whatever it is, I don't think their existence means our love is conditional. For if love was conditional on those expectations being met, wouldn't we be able to simply switch it on and off at will?

I think it's interesting too, that while our ability to love is what makes us human, it's also our greatest weakness-and doesn't that then, make it our greatest flaw?
