A smile is a curve, that sets
everything straight. Use it,
when you can and don't be
irate. Let your hair down,
once in a while, purse your
lips and then, smile. It will
not alter your looks, in any
way, or crinkle up your face.
It makes you look a lot better
and puts you back, in the
human race. No one likes
looking at a dead pan all
the time. It has a negative
affect on you. But when you're
near someone, who has a
beautiful smile, oh, what that
smile, can do!
