In and out of the house

Olivia and Sydney were playing inside the house at the playground. They enjoyed looking at each other from opposite parts of the house.The girls took turns being in and out of the house; first Olivia went into the house and Sydney went out. Then Sydney went into the house and Olivia went out. The girls seemed to enjoy their play, especially looking at each other through the house's window.To me it was very sweet to watch the two finding so much enjoyment in such simple social play. The little joys of life!
