I can be so blown away by story lines.

I've had moments of thinking maybe I should go on Twitter. It's something that I've been shy about, and I've thought that maybe I should do it.

I think the first time I realised Downton Abbey was a hit was when I was sitting in a tea shop in New York and the couple next to me were talking about Downton Abbey, and then they recognised me.

The last time I cried? My godchildren went to see Taylor Swift in concert and got to meet her. They literally ran toward her and hugged her, and it was amazing. I got big bonus points for it. I'll remind them when they're teenagers.

Being in the same scenes as Maggie Smith and Shirley MacLaine is something I will never forget.

For years, I was often afraid to speak up when I didn't fully understand a script. I'd tie myself in knots.

I don't get recognized all the time, but it tends to happen more in America, and people are so lovely when they do.
