In this GIF, Greta Thunberg's face falls into a glare when POTUS Trump walks into the UN. When have you felt such utter disappointment and hatred that's displayed on Greta's face? Greta is a teenage climate activist, and she went to the United Nations to give a speech promoting climate reform. She is not a fan of President Donald Trump, and she glares at him when he makes an entrance at the UN. Use this meme template when something is glaring at someone else from the background.
