Yes, put your 'best' foot forward and hide the kids who might tell the truth. Given that Ed Cons know the kids allegedly have 'problems', they of all people should be fine with viewing kids on restriction. But, they can't have their 'pleasurable' visit spoiled with the images of kids being provided inadequate calories and variety of food and given a time limit in which to eat. Then being PTd or restrained if they don't throw their plate away when trash comes by. Might also offend some to observe the kids taking their meals outside the cafeteria on the curb, or being banned from speaking (all day) and punished if they do so. No contact with peers and no dorm time. Some may also find it offensive to see a kid scrubbing a dumpster with a toothbrush, hauling rocks or logs, digging steps out of the side of a hill, chopping wood.
If they knew these things, which my son's Ed Con knew nothing about, they may think twice before referring to the facility. I'm sure they, and the program, would prefer they stay in the dark. They can always plead ignorance. "What? I had no idea."
