A: It’s unbelievable to watch Roger Federer beaten by 20-year-old Stefanos Tsitsipas in the Australian Open. B: Indeed. John McEnroe called it the changing of the guard during an interview of Tsitsipas after the match. Note: Changing of the guard literally refers to the ceremony at Buckingham Palace, where a group of royal guards is replaced by a new group. The ceremony, itself elaborate plus rich in history and tradition, is one of the must-see scenes in London. Changing of the guard is also an idiom, signifying some big change has taken place or is going to take place. |
