Love: What package does it come in?

Over the years men and women seem to have a definite idea of the packaging love should come in... Must be single, must not have a child, must be educated, must at least be good looking, must be a Christian, must speak good English...

But, how well does the packaging match the content especially when you start counting the days, months and years? Should pre-conceived notions, societal expectations and family doctrines determine where your heart goes?
