we always had an "expert" hanging around in the care system , in one place the "expert" cost a chap his house and wife ,
in the next place the expert had been there years and was as thick as shit , but the sun shined out of his arse , we eventually just left him to it , if he was in the room , we were not , if it got bad we all went off sick and left him to it .
lots of them "experts" around !!
