First instinct might be to think "It's the same ole Nick Kyrgios" but in this case I think the Australian Olympic Committee have a lot to answer for by needlessly stirring up a wasps nest.
Kitty Chiller (AOC) publically wondered a few weeks ago on his suitability for the Olympic team and said he was being "watched". Not helpful... particularly with a volatile athlete like Nick who has trouble biting his tongue. His comments in response were pretty tame... and then Chiller ramped it up... The whole thing snowballed and Kyrgios withdraws from the games. Way to go Kitty.
Good historical take on the snowball of words here:
