"This is the world I want for her..."

Former U.S. Marine Kevin Armentrout had been waiting to catch a plane from Las Vegas to San Diego. He was with his daughter Carter, and she was being herself -- trying to meet and say "hi" to everyone she could. But when she said "hi" to Joseph, a Samsung sales manager from Oklahoma,

he reached out and asked if she wanted to sit beside him. And for the next 45 minutes, until the plane was ready to board, Joseph taught Carter how to draw pictures on his tablet; watched cartoons with her; and even accepted her generous offer to share her snacks.  Armentrout wrote later, "Watching them at that moment, I couldn't but think, different genders, different races, different generations, and the best of friends. This is the world I want for her."
