Perhaps the most ardent longing human beings are capable of is those for truth.

For the truth about yourself. And sometimes the search for it takes crooked paths.

A boy grows up with his older brother in an intact family, his mother is a high school teacher, the father a physicist, both love their jobs and their children.

And yet the boy sometimes has the feeling that something is not what it should be.

Just a faint doubt - is something really wrong, or am I just imagining it?

What the boy sees is not just imagination: Father and older brother get on well, they share a soft spot for science.

He, Alexander, loves languages.

There are similar differences in other families too.

And yet it depresses him.
