I'm glad to hear that.
But I regret you, because German is really very difficult; -)

But
Can you give me a way to teach it myself?

Ja, ich beginne damit, dir auf deutsch zu antworten ;-)

Die Grammatik ist so schwer im Deutschen.

Although I do not understand what you say
But I would like to learn some words to fight you
I'm kidding I'll learn because I love German

As a joke, I had said:

"Yes, I'll start by answering you in German; -)
The grammar is so difficult in German."

Ah good so this is the first lesson?

Ja, das ist die erste Übung.
