Pictures showed Greta, 18, hand-feeding chips to a mystery man after taking part school climate change strike in Cairoli, Milan, on Friday. The mystery man, who was wearing a white T-shirt and a blue and white checkered bucket hat, pulled down his white face mask to his chin and Greta fed him. Greta, who donned a black T-shirt and a green frog bucket hat, appeared in good spirits as she spent time with her apparent close friend following the Fridays for Future march. The mystery man was also seen warmly putting his arm around Greta's shoulders and the eco-warrior appeared to be leaning into him as they stood in the crowds.
