Once many years ago my family went camping with my grandparents and their friends. At one point my brother who was about 6 needed to go to the bathroom and walked over to the facilities. He came back crying and said he wasn't allowed to go. When we tried to get him to explain he said "no peeing". We thought maybe there was some older kid being a bully so my Mom, Grandpa and I walked him back over to the bathroom. He ran a bit ahead an pointed at the sign out front saying "see no peeing".
