Pope Francis, who is usually calm and accommodating with his admirers, clearly lost his temper with a person who pulled on him so hard that he fell onto a child in a wheelchair.
The pontiff was greeting children in a stadium in Mexico, where he was wrapping up a trip. An over-enthusiastic well-wisher grabbed the Pope's hand and would not let go, even after he lost his balance and his chest was pressing on the child's head.
Aides stopped the 79-year-old from falling to the ground. After he returned to an upright position, his face turned angry.
He looked at the offending fan, raised his voice and said twice in Spanish: "Don't be selfish!"
