The girls were being exceptionally sweet today. They were being kind and considerate to everyone, but especially one another. They were doting on each other, playing together, and sharing without prompting. They were being deliberate in their thoughtfulness. It made me happy.

When I asked them why they were holding hands they said, "Because we love each other thiiiiiis much!"
