What a shame we have to think about such things...but we do.
There was a segment on the news concerning Stranger Danger. All the children in the study were briefed on the dangers, but when a strange man asked if they could hold the leash with his puppy while he got water, each of them cooperated. Then the man asked for the child to bring the dog to him in the shade and each child responded positively.
Just too easy!!!!
