To Smile Or Not

So I read that if one smiles during a state of unhappiness, it uplifts the mood. Realising that I have been doing the same for a while - long before I read the article - I try to figure out if it really works. Maybe it does work for some people. A smile, no matter how dimmed or feeble, does impact how people react around you. And maybe, sooner or later you start believing what's around (a state of normalcy) has seeped into what's inside. I hate pretending to be happy. More often than not, I feel I am doing it for others. So much effort to please others??? Maybe, at times. At other times, I smile for no reason at all. Whatever it is, it somehow doesn't feel...
