Do you remember that old TV series, Get Smart? Do you remember at the beginning where Maxwell Smart is walking down the secret corridor and there are all of those doors that open sideways, and upside down and gateways and stuff? I think that everyone keeps a whole bunch of doors just like this between themselves and the world. But when you're in love, all of your doors are open, and all of their doors are open. And you roller-skate down your halls together.
