The absolute gall of the people (usually pudgy, white, middle aged journo blokes who've never once had a job you couldn't do while drinking) accusing Osaka of lacking 'mental toughness'.

It takes a fuck of a lot of toughness to carry on through depression, and a lot of people have really revealed this week that they don't understand this.
Leaves more of a mark on clay. Although I hear the umpire got one badly wrong in one of the women's semi finals yesterday
