The real trouble with learning most languages outside of English, is in English, we have a very casual way of approaching our own language. No one speaks with perfect grammar, and slang is extremely commonplace. This is great for English learners, because as long as you get most of the words out, everyone will understand what you meant. In German, if you don't speak it with utmost clarity and if you don't 100% nail the word order, people will look at you as if you have a learning disability.
