This post is for the German native to get a couple of tools at hand, to not make the same mistakes, I made in the past and actually be understood right away. Of course it's also for the English native to understand the German in your life a little better. (Mental note: Send link of this post to Terry!)
This is just a small selection of the things that are different. There are tons of expressions that are the same in the English and German language.
If you have anything to add, please free to leave a comment! ;-)
