Good one, Greta! Greta Thunberg recently turned 18 years old and she shared the perfect joke about her plans for the day.

Taking to Twitter on January 3, the Swedish climate activist shared a new selfie while thanking fans for their birthday well-wishes.

She went on to joke, “Tonight you will find me down at the local pub exposing all the dark secrets behind the climate- and school strike conspiracy and my evil handlers who can no longer control me!”

“I am free at last!!” added the 18-year-old.

It’s likely a jab at Thunberg’s critics, who sometimes suggest the teen has been “indoctrinated” by her parents.

It’s not the first time the activist has used social media to get sassy with her critics.

Back in November, following the U.S. presidential election, Thunberg went viral after using Donald Trump’s criticism of her against him.

In September, she also took aim at a death metal music video that appeared to mock her.

Instead of calling out the video’s creators, she promised in a hilarious message to move on “from this climate thing” and dedicate her time to death metal music only.
