If you’ve been watching the US Open this year, chances are you’ll have seen that there’s been some drama on the court. There was a heated exchange between players Jelena Ostapenko and Taylor Townsend. Ostapenko has been fined in the past before for throwing her water bottle and knocking over a chair, after she lost a match.

So today, we’re talking about bad behaviour in tennis, and what the rules are for tennis players who throw things, shout, and even smash up their rackets. Someone who has seen many a Grand Slam spat in their time is Ben Rothenberg, former NYT tennis correspondent and writer behind the blog Bounces. He takes us through some top tennis meltdowns and explains why it’s such a high pressure sport.

Am I a narcissist? Am I dating a narcissist? Is narcissism becoming more common? How do I spot a narcissist? Can narcissists change or be treated?

These are just some of the many questions which people - especially on social media - ask about narcissism. It’s a term which gets banded around A LOT these days, but what actually is it? Well, we took five of the most asked questions about narcissism and put them to an expert. In this episode we sit down with Ramani Durvasula (@DoctorRamani on YouTube) - a bestselling author, clinical psychologist and leading expert on narcissism and narcissistic relationships.

And, just to be clear, in this episode we’re talking about the narcissism as a personality style not the diagnosable disorder. There’s a big difference. Narcissism is a spectrum of several behaviours and characteristics - like being overly sensitive to criticism and having an unshakeable belief you’re better or more deserving than other people. But Narcissistic Personality Disorder (NPD) is more rare and much more extreme — it’s a diagnosed mental health condition where a person demonstrates many of the traits repeatedly and over time, and these traits significantly interfere with a person's life.

There have been huge protests across Indonesia. They were sparked by cost-of-living concerns and discontent at politician wages and allowances. But after police ran over and killed a delivery driver, protests have spread and become violent. Protesters have been killed, buildings torched and politicians' houses looted.

Astudestra Ajengrastri, a BBC journalist who’s based in Jakarta, takes us through why the protests began, what the government says about it, and where things could go next.
