No matter how many frustrations come along, or how many problems arise, I never lose the feeling of how lucky I am. I'm so pleased to be doing a job that makes me laugh every day. I'm aware that it's a huge privilege.

You feel you can pretend to be young until you're 50, but after that, what happens and how do you approach it?

I've never for a second felt like my job has been more of a struggle because I'm a woman.

I'm the person who will go to a wedding and switch the place cards around because I don't want to sit next to someone I don't know, because I'm so bad at chatting to strangers.

I think that there's an idea in 2016 that if a woman doesn't have it all then she's lacking in some way, and I think that 'having it all' is the kid, the relationship and the career, and that seems horribly skewed. I get genuinely excited when I meet women - or men - who don't want to have children. It's refreshing and unusual and means they're not swayed by what society has told them, they're just listening to their own basic instincts. I love meeting people who are fulfilled by other things. I think, 'lucky old you' when I meet someone single.

I started writing sketches with Dennis Kelly, who I ended up writing 'Pulling' with. We entered a BBC competition and did quite well, then started writing bits for other people's shows. You wheedle your way in, write pilots and eventually you end up writing a sitcom.
