Sometimes boredom is not satisfied, then let the smile remained. Keep smiling ... even if it does not make us feel much better. (Concern, whether it be in the form of "words and letters" but I have always meant).
Sometimes that disgusted not satisfied, ask for a smile still keep smiling to them ... even if it didn't make me feel much better (not concerned that it will be in the format "the words or letters" last meaningful date)
Sometimes I wish that the Fed is not satisfied with a smile is still saying to smile ... even if it is not, we feel much better (not that it would be concerned about it in the form "words or letter." They are always meaning).
