My 11 year old ds and friend were given permission to go to the park to play today. At 12.30pm I sent older son to park to say it was lunchtime and could they come back. Instead of doing this they went to another boy's house to play without permission. I stomped round and extracted them and sent playdate boy home as I was furious that they thought it was ok to go where they wanted without permission - did I overreact??
