Momo by Michael Ende

I have been dragging around this book for almost 2 years and never managed to finish it. The story is too heavy (although it looks like a kid' story book). I don't really like to think when I'm reading for leisure.

All dwelling in one house are strange brothers three,
as unlike as any three brothers could be,
yet try as you may to tell brother from brother,
you'll find that the trio resemble each other.
the first isn't there, though he'll come beyond doubt. - Future
The second's departed, so he's not about. - Past
the third and the smallest is right on the spot,
and manage without him the others could not. - Now
- The past consists of moments gone by and the future of moments to come, so neither of them could exist without the present. -

Yet the third is a factor with which to be reckoned
because the first brother turns into the second.
- The present exists only becasue the future turns into the past. -

You cannot stand back and observe number three,
for one of the others is all you will see.
- There's really no such thing as the present, only past and future. Take this moment, for instance: by the time I talk about it, it's already in the past. -

[...] are the three of them one?
Or are there but two. Or could there be none?
- You could be forgiven for thinking there was only one brother - the present [...] or only the past of the future. Or none of them at all, because each of them exists only when the others do.-

Just name them, and you will realize
that each rules a kingdom of infinite size.
They rule it together and are it as well. - Time
In that, they're alike, so where do they dwell? - The world
