I have 4 kids. Today we set out on a well-known walk through woods to a park- about an hour away. The kids know where to wait for us if they get ahead, when they're on scooters. Near the beginning of the walk, the middle 2, aged 8 and 9 disappeared- we thought they'd gone ahead as they had a scooter. At each possible waiting point there was no sign of them, so we reasonably concluded they had crossed all the roads and arrived at the park before us. That would have earned them a verbal roasting. They were not at the park so we looked for them all over the town, eventually hiring a car and going to see if, by any chance, they had gone home, before phoning the police. They were at home. Right at the beginning of the walk, they had deliberately hidden behing a tree until we had passed and calmly gone home. They have also been going out of their bedroom windows at night. Normally, they are very well - behaved, and nobody could believe them capable of this. What would you say? What would you do? We are still shaking, and lost for words.
