Not only did she write one of the greatest and most loved characters in children’s literature to date, JK Rowling is also a quick-witted member of the Twitterati.

Today the writer celebrates her 50th birthday, and it’s also Harry Potter’s 35th birthday too.

To celebrate the day, here are some of her best and most brilliant tweets.

JK doesn’t pretend writing is easy.

But sometimes she finds it hard not to get distracted…

And she shares her words of wisdom with her 5 million followers.

All that money and fame hasn’t gone to her head.

And while she is normally a very private person, on Twitter she shares her true feelings.

She takes the world of Harry Potter just as seriously as we do.

And she knows how to inspire her fans.

And she has time for them.

But she also has time to shoot down trolls with her razor-sharp tongue.

And stand up for what she believes in.

And JK Rowling is really very funny.
