Downton Abbey waltzed back on to our screen last night, to the gratitude of the nation. It will come as no surprise that this is one of my favourite shows, not just because of the drama and characters but also the etiquette, customs and clearly defined class structure that was present at the time.

The custom of pouring wine right up the top of the glass is something only modern (high street) restaurants do. For a moment last night the dining table of Downton looked like Pizza Express.

Episode 3, perhaps my favourite one of the series to date, contained relatively few etiquette slip-ups, which for a large chunk of the episode worried me that I would have nothing to say! But, panic not, I found some, as well as some other interesting matters of note.
