On this picture, we can see eight people, where four boys splash in the water. On the rock, we see a little boy watching his friends (family?) Swim while his mom gives the shell to another boy, probably a son. The boys are building a sand castle. the boy is eating ice cream next to them, it is very tasty, based on his facial expressions. A sunny day at the beach gives the family a lot of fun and memorable experiences.
