Small steps for bashful sister, proud smile from older sister

The younger sister/friend in pink is timidly building her sand castle away from her other peers. She had always been extremely shy and would usually play alone. For the first time in a long while, the girl in pink lets herself enjoy playing with others, albeit with some boundaries still. Even so, the older sister/friend in red polka dot dress looks on appreciatingly, proud of the progress made by her sister/friend.
