I've read lots of threads that refer to 'feral children'. Having lived outside the U.K. For 10 years, I'm not quite sure what's meant by this - it seems to be an expression that's recently come into use. My sister in law from England, who was over here a while back, refered to many of the young neighbourhood children who play outside and go in and out of each others' houses as 'feral'. I would have thought this was pretty normal behaviour for young children but 'feral children' seems to have a pretty negative connotation.
What would be your definition of 'feral children'?
