One day, you don't feel like doing anything. Nothing interests you, everything bores you. Feel more and more empty inside, more and more dissatisfied with yourself and the world in general. Then even that feeling wears off, and you don't feel anything anymore. You become completely indifferent to what goes on around you... You forget how to laugh and cry - you're cold inside and incapable of loving anything or anyone... There's no going back... The disease has a name. It's called deadly tedium.

There were doors that looked like large keyholes, others that resembled the entrances to caves, there were golden doors, some were padded and some were studded with nails, some were paper-thin and others as thick as the doors of treasure houses; there was one that looked like a giant's mouth and another that had to be opened like a drawbridge, one that suggested a big ear and one that was made of gingerbread, one that was shaped like an oven door, and one that had to be unbuttoned.

Lots of things take time, and time was Momo's only form of wealth.
