This is the third time I've photographed these little girls, and I entered their home on a rainy Massachusetts morning to big hugs and shouts of "Miss Erin!" The whole session felt like a play date. The dog ran wild. The girls showed off their speed. Umbrellas didn't keep us dry. And it mattered not. Once again, real life, among sisters, looks like love. It doesn't get better than that, even if the session ends with a downpour.
