Smiling but Depressed

We all have that one friend, that one person we know that is always happy and smiling, never angry or upset, just calm and peaceful. That one person where it seems like their life is perfect and they have no problems or issues. That one person we all go to vent to and just tell why we hate our lives but we never really ask them. We may not know it but they are always there for us when we need them but who is there for them. We never question their life behind closed doors we just assume that it is all cupcakes and rainbows. But what really happens behind those doors, is the smile real or just a mask for what they are really feeling. Maybe think twice before you assume someones decisions in life.
