Ok, not everyone is familiar with Great Expectations. Not everyone is a fan of Dickens.
However. It is not Mrs Haversham, Miss Haversham or any other variant which crops up frequently on here.
Someone has a user name including "Miss Haversham", which I find very annoying. It's Miss Havisham . So I'm having my pedantic rant on here, rather than correcting them. Rant over, but I may be back. As you were.
