Do any instructors out there think you should tell your students not to ski the zipper line? That's it's "too easy?" One should never ski the zipper line?
I would hope an instructor would get laughed out of any respectable ski school with such statements.
Sure,it sounds silly at face value, but it's tough without knowing the context and tone of the statement, the make up of the class, and the classes own preconceptions of the 'only' outcome. Sometimes a statement that creates an 'oh yeah?' challenge can be pretty fun. We also might have missed the part later that said, "now that I've said and done that, let me prove us wrong!" That can be fun as well!
I mean this looks fun too...
