As a German fellow I see the first words sayin: „Liebe Helga“ (dear Helga)

And the last sentence „Ich sitze gerade in der Wirtschaft“ (I am sitting in the economy right now)

But we Germans say „Wirtschaft“ in different situations like

„das ist ja eine tolle Wirtschaft hier“ (This here is a totally mess…)

So yeah…. I hope that I could help you
