Grin Worth a Smile, January 2011 | i assume we expect that a beautiful smile should come with a mouth filled with pearly whites, perfect and in their proper place. but in my new findings, a beautiful smile is made up of a warm and genuine heart that is displayed through the expression on ones face. joy sprung on his face without hesitation, without teeth to display. it was beautiful. our expectations are sometimes set higher than the true value of what we are expecting.
