I discovered that some of our schools are not reinforcing our politeness training. A friend who had a disabled child was told that he did not need to learn how to sign please and thank you as that wasnt important! Another friend's daughter was told she should only respond yes or no in class, not yes ma'am/no ma'am! And my DGS is not required by his speech therapist to do so either. So it makes our job as parents/ grandparents that much more difficult.
