NB: the title isn't "what is love" because the only acceptable response to that would be "baby don't hurt me, don't hurt me, no more" 
I have no idea why I'm asking this, I just thought it would be interesting to see how different people define love, because I really don't know how to put it into words. I'm not a journo or anything like that, I promise! Just interested 
So, in summary... what IS love?
