What is love?

A couple of minutes ago I got an SMS from a dear friend quoting "what is love?".

"Love is the irresistible desire to be irresistibly desired" was the explanation. Beautiful, isn't it? But is it true? we have been taught(in songs, movies, novels, friends) that love is all about giving and not expecting and bull shit.. so why this irresistible desire when you are not suppose to expect?

what if the desire is to be loved from many? thats GREED :) .... but desire is only the other form of greed? so whats the difference? I dont know... I would like to know, though!
