Sheila and Mr. Birling have very different characteristics. Sheila, being a much younger person is quite impressionable, whereas Mr. Birling is not he believes in the solid way of what he thinks is right must go ideas. Sheila attitude and views change as the as the inspector goes on, while Mr Birling refuses to change what he thinks altogether.
