No one else will take out the garbage or change the light bulbs. In order to get things done, singles must do it themselves. Singles are free. They can go to the movies when they want, buy the outfit they want, clean house whenever. They have dollars they can spend on themselves.
Singles are lonely.
They don't have anyone in whose life they are number one. They don't have anyone to buy them flowers, take them to dinner or share their intimate thoughts and dreams. Singles are often uncommitted. If something doesn't benefit them, they won't do it. Singles want to belong, to fit in somewhere.
