Once a happy lady turned to a disaster when she met you she tought life is full of joy but no, life plays with you like a toy she tought the man is her joy but she stands incorrect she waits on top a hill for the man but he fails he fails to come she falls straight into the ground crying and all wounded then she learns to stand and, be dependent she learns to smile tough her heart breaking she still smiles Inside still healing but you're not the reason behind it its her own confidence that made her smile
There is no history behind a smile Its just a natural thing I didnt read the read i just commented Soz
Well at some point we would've had to develop the facial muscles required to smile and to associate that with happiness sooo there's history
