If you ever call in unannounced to the nursery that can be interesting ! I called in one day to pick up a beaker to find all the nurses chatting and ignoring the children. A friend once called in to her son's nursery to pick him up and found him tucking into a pot of glue ! And a friend decided not to go out to work after visiting a nursery to see what it was like to find a neighbours child upset in a playpen, had been obviously upset for a while as her face was a mess and nose running badly and no-one doing anything to help her.
