This ad for Facebook show different groups of friends, experiencing life together. "Our Friends" They make our lives a little different, leave us a little bit changed. So we leave behind proof of the time we spent together. Some will show us that we actually like country music or help us find our favorite Indian food. They drag us into their madness, make us heroes in their stories. So we let their likes become our likes, and the things they share become the things we share. They challenge our point of view, push us out of what's comfortable and we trust them just enough to follow. But each changes us, even if just by a little. Each shifts the trajectory of our life simply by being our friend. Friends Facebook
