The three little pigs.
One built his house with straw and the another with sticks.
The only one who managed to built a decent anything was the piggy who built his house on a strong foundation and walls made of bricks!
The moral of the story is not only do we need some pretty strong defences to keep the wolves out but also that anything constructed on a weak foundation is bound to crumble.
It's a pretty sweet metaphor for relationships and dating as well: Put time into laying stable emotional foundations and you'll have your dream relationship; build your relationship on lust or money and it'll crumble and blow away.
