Is this anything like the small mob of teenagers (16-18 year olds) I ended up looking after last weekend suddenly deciding to go camping? In October? About ten minutes after I'd gone to bed thinking they were all safely settled?
The last stray one turned up around lunchtime the next day. I was so near ringing her mum, only the fact that one of the more reliable ones had sworn on her mother's grave that she was fine had stopped me.
