I recently discovered the wonderful poems of gGerman writer Erich Kästner.

Always capitalize names of countries and nationalities

I previously had a vague idea of him and his life but iI honestly never imagined his poems towould be that good.

Always capitalize "I"

For the vast majority of person iople I know, Kästner is known for one thing: his books for children.

His works are classics of children's literature in gGermany.

NSome notable works are, for example, "Emil and the Detectives" and "The Flying Classroom".

I, mMuch to my surprise while looking back at it, I never had any contact with them when iI was young.

I didn'tneither read them nor listened to them.

You could also write: "I didn't read them or listen to them", the meaning is the same. But with "nor" you should use "neither"

But a few weeks ago iI read an interesting poem titled "Das Eisenbahngleichnis" by Kästner.

It's dated to 1933 and is describinges the continuous travel to the sense in life.This simple poem catchedught my attention and iI had a sudden urge to get a collection of his poems.

I don't understand what this means: " the continuous travel to the sense in life"

He constantly uses a rather simple language but still achievmanages to trigger feelings and memories.

You could write "manages to" or "is able to", or you could simply write "still triggers feelings...", but "achieves to" is not right

In contraryst, he is portrayings the adult world as a dark place, influenced by unethical parents.

While iI wouldn't agree with him (since my lecture of "The Lord of the Flies" iI have learned a lot about violence from children), iI have to admit that iI find his ideas quite interesting and innovative.

It's thea story about a moralist in the bBerlin of the early 30s.

I read it quite a while ago and didn't really enjoy it.

I can't really narrow it down to a simple aspect, it's rather the whole story that iI didn't really get into.
