Listen. This is very important and I cannot stress it enough. If you’re a non-British fic writer and are writing a fic set in the UK, no-one has a whistling kettle. Literally everyone uses an electric kettle, for everything you could possibly imagine using hot water for. Tea, coffee, boiling pasta, potatoes, vegetables, doing the washing up – kettle. Electric kettle. Nothing betrays an American fic writer quicker than “the sound of the kettle whistling”. Really messes with my suspension of disbelief man >.>
