Smile because it's the only thing keeping you sane,
Smile because if you don't, you will fall off the edge quicker then what you imagined hell to be like.
Smile because losing someone you love to death or even to the hands of another hurts you so much it's your only option.
Smile because if you don't you know they will ask you your reasons and the fact that they are unexplainable doesn't satisfy their inquisitive nature.
Smile because from an outer appearance you look normal but from the inside, you're fighting the voices in your head, screaming in pain when no one can hear you.
Smile because we live in a society were happiness is mainly produced from evil, and the destruction of others fuel many with power.
Smile because its your only form of defense.
Smile because its your last effort of normalcy.
Just, smile.
