What is "love" to a lay person?

As a budding Buddhist, one cannot help but investigate day to day phenomena with the magnificent tools made available to us by the Buddha. An interesting thought occurred to me today and prompted me to ponder the nature of love. The conclusion that was arrived at the end of this particular stream of consciousness is that love is non hate, non greed, and (hopefully) non delusional. It is experiential, highly conditional, impinges on all faculties, and reverberates through the heartstring. As with all formations, it is impermanent. Wordly beings crave it, but few truly uncover it. How do other lay people conceptualize love? And how would a monk approach this investigation?
