Quick story about politeness. During Alex's second transplant she suffered a Grand Mal seizure as a result of the anti-rejection medication that she was on. By the time we got her to the ER she had completely lost the ability to speak. Well actually she lost ALMOST all her speech. Whenever she would burp, she would say "excuse me"! The nurses were looking at us like what have you done to this child to make her so polite, even when she's having a seizure! My wife told them "Honestly we don't beat our children to make them polite!" ;-)

P.S. Obviously politeness is located outside the speech center of the brain...
