I think this can go both ways. I've had instructors say that something is difficult when it was easy for me - and then I start wondering what I missed. When you're an instructor, you never know when a phrase will encourage or discourage someone and it takes a while to figure out what works with each particular student. (I've had the same thing happen when I supervise employees - some of them are very sensitive to criticism, and others don't seem to realize that you are criticizing.)
And who knows, maybe someday that lightbulb will go on and the new technique will click and then it *will* be easy.
