Also you know that a smile does not cost you, do not even need a power of strength , he only uses a few muscles in your face ...
Brother ...Smile for your brother is cool , like the coolness reservoir wetting foliage , your smile is the antidote to the sad caution , encouragement for flagging souls , do you treat lightly this charity
Brother ...Try to think of it, if you are in an unfamiliar place , no family and relatives , acquaintances and no friends , no one can smile and say hello to you ... how did you feel then?
Or when you are in a state of grief , or pain ... and all the people even frown on you ? How you feel at the time? Course you will feel worse and more pain , whereas drugs from doctors never the less , fruits and other food is always served in your room ... then what do you expect ? ? ? between you expect is a smile.
