The look of love, that un-expainable expression a parent or child has for the one they love. A mix of joy, pride, care, excitement and confidence. It's the smile that changes the world for just one person. They don't see the 'flaws' you see, just their incredible mother or daughter, all her strengths, beauty and personality. 
The captivating Wendy and Pat smiled this smile all day, and I love it.
