"She replied saying Trinity could come down for a tour and a bit of a chat - she showed Trinity a really good time."
Trinity said she loved everything about meeting Mrs Chadwick.
"It was amazing being shown around and getting to ask the mayor lots of questions.
"I asked her how a person becomes a mayor and how hard it is to become a mayor. I also asked what life was like being the mayor."
Trinity said if she ever found herself in the position, the first thing she would do would be tell the public about all the changes she would make.
Mrs Chadwick said she enjoyed meeting Trinity who had some innovative ideas and asked some probing questions.
She said finding out what young people thought was a big part of consultation with the community.
