My mother volunteered a LOT at the OKC zoo. She had the highest number of hours volunteered for many years. She often had to deal with a school class or even large families. She had succesfully managed to raise my brother and myself into adulthood and we never get arrested!
She did not put up with any kid anywhere getting out of line. She had her Docent uniform and she knew how to use it. She even told some adults to straighten up and act right.
She often had to line up a group of kid to greet them and get their full attention. She had some funny stories and some of the kids and parents essentially got a time out.
She called this gorilla one my sister.
