As I see, most of the question is about some interesting/uncommon questions of German learners. What I also see, they are often not understable by the native speakers or they find it too trivial. The same problems are coming often in the IRL life, fortunately here the voting-commenting mechanism provides a communication standard where we can continously clarify-clean our questions until they will be mutually understable and also grammatically clean. :-)
That is ok, but I think, answering these questions is not so funny for a native speaker. Or it is?
