My difficult child took off and we could not find him. I had the phone in my hand and was about to call 911! He is allowed to ride his bike in front of our house and down into the cul-de-sac (which is only 1 house past our's). There is a kid up the street about 5 or 6 houses from our's that he recently started playing with (this is further than the cul-de-sac so he is not allowed to go there unless we know). Yesterday he played with him at his house and when it was time to leave the parents said he could come back over today. difficult child was up bright and early wanting to go over - but we made him wait until 10 am. When he went over the mom told him their son could play in 2 hours (12 noon) and they would come down to get him. So he cried and screamed and yelled for at least the first hour and then waited the rest of the time. Well about 12:20 no one had come down so HE LEFT without telling us. My husband went to their house and knocked twice, no answer. We were both freaking out. His bike was still outside our house. We searched the house for him and all over the neighborhood. Finally I walked down there in the pouring rain and rang the doorbell until he came to the door, and then the mother, and then the son. I told him he needed to come home right away that we were worried because he did not ask to go there and of course he flipped out and screamed and went limp so I couldn't haul his 52 lb body back home so I practically had to drag him by the arm. We had a long talk about safety, etc. I need some ideas or suggestions for making this kind of thing sink in his head. I thought about even calling the non-emergency # of the police to see if they would come over and scare him into following our rules. Has anyone had any experience with this type of thing? I don't know what to do and it scared me to death.
