We're used to the characters of Downton Abbey sticking to the correct rules of social behaviour, but last night Lady Mary delivered perhaps the most 'Downton' Downton Abbey line of them all:
"I'm going upstairs to take off my hat."
It was met by looks of complete understanding at Downton. Of course you go upstairs to take off your hat...
It's a lesson viewers are taking notice of.
It can be a new 'go to' when a conversation gets dull
Panic as we ponder whether we've been breaking the rules all these years
Some have already found fault with the plan
If you took it off upstairs you'd never have to ask this...
People hope to adopt the phrase in all walks of life
Of course, it could mean something else entirely
We could indeed make a whole game out of this
But actually, she probably just didn't want us to see her hat hair.
Downton Abbey continues next week at 9:00pm on ITV
