I once played a locked dementia room one man wanted to help me pack my gear. I had him hold the mic stand and told him it will be the last item to go on the Rock n Roller cart. This man had no outwards that I could tell of dementia. He put the mic stand on the cart, I fastened the bungee cords and he proceeded to follow me out the door, that is until an nursing assistant stopped him from leaving. That was the last time anyone helped me load the RnR cart.
