picked off bits of blouse off the burn.Because if you pull the clothes that are stuck to the burn,you would pull the tissue under clothes off too.This would cause more damage to the burn.He shouldnt have placed butter on the burn because it would prevent the heat from escaping and cause infection.He shouldnt have put a wet but a dry bandage on the burn.Tell right from wrong;Indicate where it is
