Lesson 1 If you are in a position where you have to wake people up in the morning, Do not make any derogatory comments like "get up lazy bones" or "if you don't get up now, you are proving that you never get anything done...".

People who look forward to a bright day and tell themselves they will be able to accomplish a lot, find it much easier to wake up with enthusiasm.
Lesson 2 If someone does something that wastes your money, i.e. throwing out food that could still be eaten, do not speak in a manner that would be onaas devarim. Especially when the loss is minimal, badgering someone about inconsequential matters creates resentment and animosity. The loss of peace of mind and tranquility is much greater than the loss of money.
