Great Britain's Hopman Cup pairing of Laura Robson and Andy Murray have spent the whole tournament taking the mickey out of each other - and the pair have loved every second of it.
Confidence is something 15-year-old Robson clearly doesn't lack.
The cheeky teenager, who was born in Melbourne and has family links in Perth, hasn't taken a backward step in a jovial verbal stoush with world No.4 Murray.
"I've only known her for a year and a half and we haven't said too many nice things to each other during that time," Murray said with a laugh.
"I guess that's just the way our relationship is."
Despite Robson's tender age, she is quickly building up a reputation of asking some rather ditsy questions on court.
Another of these moments was brought up by Murray following their doubles win over Germany on Wednesday.
Murray: "We walked back to the baseline and Laura asked where the balls were. I had to explain to her that it was the opponents' serve."
Robson: "It was an honest mistake."
Murray: "I don't think she quite understands the scoring system yet."
Robson (a bit flustered by now): "No, I mean, no."
The world No.403 hit back later in the press conference, saying she was yet to decide whether to take up Murray's offer to team up for the 2012 London Olympics.
"I'll have to think about it," she said with a smile.
Robson set tongues wagging after winning the junior Wimbledon singles title at the age of 14.
But despite all the media hype she has encountered since then, Robson has kept her feet firmly planted on the ground.
She also lets her glowing personality shine at every opportunity.
Asked what part of her game she would particularly like to improve, Robson replied: "Just everything really, in particular my through the leg shot and stuff like that.
"I'm planning on using it more often."
Robson, who put in an impressive display in her loss to German Sabine Lisicki on Wednesday, faces one of the most challenging tasks of her fledgling career when she tackles world No.5 Elena Dementieva on Friday.
Great Britain will secure a spot in Saturday's final should they beat Russia and Robson was looking forward to her first match-up against a top-10 player.
"It's going to be a good experience ... I've got nothing to lose really so I can just relax and play nice, flowing tennis," she said. Murray will face Igor Andreev in the men's singles rubber.About the Author:
