They think happiness is a bouquet of helium balloons. Picture everyone in the world, each holding a bunch of balloons on strings. Most people's balloons are plump and bouncy, and they float really well. Some people's balloons might be droopy because they're sad, or sick or something. So the people that know me think my balloons are just droopy, and they try to help. They say, "Here, have some helium. Let's get your balloons all floaty again." But I'm not holding any balloons at all. So even if they gave me helium- tanks and tanks of it- there's nothing to put it in. My balloons are just completely missing.
