Accents
One thing Eileen did not get right in the immediate aftermath of her defection was her chosen accent. Kirkham is set in Hampshire and the residents have a distinctive lilt to their voices. Eileen has not. What Eileen managed to do was copy human like speech but without any of its "oddities". So she has no accent and it has taken her decades to master local turns of phrase and so on. Eileen admires other accents though and likes a soft Scottish one best.
Portrayal of Fantasy Characters
Eileen watches the occasional fantasy film with Derek and has to stop herself coming out with acerbic comments as to how different magical folk are portrayed. She watches more science fiction (notably Star Trek) and finds this easier to cope with given there was nothing like this in the Fairy Kingdom's fairyvision system and she can come to the programmes with no prejudices.
Taxation
Not popular in the Kingdom. Not popular on Earth. Eileen hated it equally in both places (she'd hate it less if she was sure it wasn't wasted). Has every sympathy with hard working people moaning at the government over this.
