Yesterday I saw a photo of two good friends laughing, and it made me so happy. It reminded me of a similar one I have on my fridge of myself giggling with an old friend, and countless other snapshots of my sisters and me doing the same thing. These are my favorite pictures. You may not know what they're laughing about, who the people in the photos even are—and theirs might not be the prettiest-looking facial expressions, either—but it's obvious they're definitely having fun. What I especially love about these types of snapshots are the way they capture a truly spontaneous moment. Laughing, at least authentically, isn't just something you can just do on command. It just happens. And then, there! You have that beautiful, hilarious little outburst saved forever.
