I do so many things. Like when I was younger, if I drove past a house that I didn't want to live in, I'd hold my breath. Driving around somewhere like Slough I'd go blue in the face.

On the surface, it's really easy to dismiss certain characters, but sometimes you find that the most interesting parts are disappointingly shallow. It's your job as an actress to pull that person apart, and work out why they act the way that they do.

I like to accessorise shirts with a little ribbon tied round my collar or a country style ascot. I've also sewed little hearts on some of my sleeves which I've done for years because I always wear my heart on my sleeve so if you see a little embroidered heart on my clothes, that's why!

Sometimes when a scene is written or directed to be shouted or played incredibly angrily, I always think it's way more terrifying when someone is fuming and talks in a very calm way. I always want people to shout at me if they're angry - it freaks me out that whole thing of, 'I'm not angry I'm just disappointed.'

Performance became part of my art in a way - expressing things and emotion.

I love when people become obsessed with Downton.

At 17, we all think we know what we're doing.
