Children are fun to photograph.  The beach is fun to photograph.  Children on the beach are thus fun to photograph...right?  This little one is a handful, and I happened to catch her running up from the water's edge none too happy with the wet and sandy nature of her hands and clothes.  I love the expression she shot at me when she saw the camera.
Again, sorry about the EXIF, getting it sorted.  For now, here it is Nikon D7100, f/5.6, 1/640, ISO 100
