"Hard to understand?" Is a question more complex than it might appear on the surface. There are obvious examples of ambiguity in speech which lead to complete misunderstanding.

But "hard to understand?" may also satisfy the criteria of "effort to understand". Just because a message was understood does not mean the audience was able to hear it effortlessly. And that boils down to consideration.

It's a two way street. Correcting mistakes because of apparent lack of effort is probably not warranted, but a speaker is not entitled to a happy audience either

I agree completely and have nothing to add, but I felt compelled to put my username under both of yours.
