Smiles are made of love and happiness but sometimes they are made of pain.People often see  someone smile and think that they are happy and have no pain in that smile.The people who smile the most are usually the ones that are in the most pain.I guess that’s why most people can hide the fact that they are sad and once you smile to pretend to be happy you do it 24/7 because then people won’t be constantly asking if you are ok.
