Hi This is a good article and definitely if practiced would enable one and all enhance culture and values and would be helpful in having more family and friendly environment and one would start loving his/her office. But it has to be practiced by all.It could be difficult for one to keep smiling and greeting others despite not getting any reciprocation. The artcile should have also addressed how we should handle situations when does not get any reciprocations. Must know how we can help others to learns these?
