I have some family members with a learning disability and 4 cousins with Down syndrome. The way I answered the OP was in fact in a way that a teacher would have. Explain the problem while being stern and understanding.
I would not have gotten quite as rude as some did. I myself (as admitted in another OP's thread) have aspergers syndrome. Because of this I do not like nor do I understand most humans. My memory is terrible as well. But here I try to help out as much as I can and if I answer something wrong I welcome any corrections I may get. Maybe my post with the links will give the OP enough info to help him, so that his next set of threads will be more involved. That is the goal here.
