16-year-old climate change activist Greta Thunberg can’t be bothered with discussing global warming with President Trump.

In an interview with BBC radio’s Today program on Monday, Thunberg said that talking to Trump at a United Nations summit on global warming would be a waste of time, since he wouldn’t pay attention in the first place.

“Honestly, I don’t think I would have said anything because obviously he’s not listening to scientists and experts, so why would he listen to me?” Thunberg said. “So I probably wouldn’t have said anything, I wouldn’t have wasted my time.”

Earlier this month, Trump attacked Thunberg in a tweet after Time Magazine honored her as its 2019 Person of the Year. The President accused Thunberg of having an “Anger Management problem” and mockingly suggested that she “go to a good old fashioned movie with a friend.”

Although Thunberg at the time didn’t directly respond to Trump’s tweet, her Twitter bio appeared to clap back at the President by saying: “A teenager working on her anger management problem. Currently chilling and watching a good old fashioned movie with a friend.”

In response to the Trump tweet earlier this month, Thunberg said that she found Trump’s personal attacks against her as “just funny because they obviously don’t mean anything.”

“Those attacks are just funny because they obviously don’t mean anything,” she said. “I guess of course it means something — they are terrified of young people bringing change which they don’t want — but that is just proof that we are actually doing something and that they see us as some kind of threat.”

Her father Svante Thunberg chimed in during the interview and said that his daughter managed “the fake news, all the things that people try to fabricate about her, the hate that that generates” well.

“Quite frankly, I don’t know how she does it, but she laughs most of the time. She finds it hilarious,” Svante Thunberg said.
