It says the kids urinated on the girl....which implies the rest of the kids were all boys.
Disturbing behavior for kids that age. I hope that mother of the 5 year old girl supervises her and her playmates from now on, and I hope she thinks twice about letting her play with boys two years older than her. I wonder how often they’ve persuaded her to play doctor? I don’t know how many 7 year old boys would normally play with a five year old boy let alone girl if not to take advantage of them.
