I started to care about the stuff we read in school in my early thirties (Shakespeare would be an exception, for ... reasons).

There's a special exception for Max Frisch which I discovered mid-twenties and was very thankful I did not have to read it in school.

So, well, the "why" is: maybe later in your life.

(There's another "why" in "you an your friends aren't necessarily representative for Germany as a whole, bit that would have been a rather cheap comment)
