Australia coach Darren Lehmann has proven he's not afraid to make tough selection calls and won't shirk having tough conversations with colleagues and players - traits he is likely to exhibit this week.
But there's one topic the no-nonsense operator will refuse to broach with the selection panel as they settle on a squad for the third Test against South Africa: his son Jake.
Jake Lehmann is among the young batsmen around the country hoping for a call-up this week as chairman of selectors Rod Marsh mulls changes to the XI embarrassed by the Proteas in Hobart.
The 24-year-old had played just 18 first-class matches for South Australia and Yorkshire but averages an impressive 48.96. He was in the Australia A squad earlier this year before joining Yorkshire under Jason Gillespie, and is an unlikely call-up for the day-night Test at his home ground, Adelaide Oval.
But if the left-hander continues to produce more knocks like the unbeaten 129 he recently scored against Tasmania, and Australia's middle order continues to misfire, then that moment could come soon.
Darren Lehmann insists he has no idea what fellow selectors Rod Marsh, Mark Waugh and Trevor Hohns think about his son.
"I don't sit in on anything when they (selectors) talk about Jake," Lehmann said.
"I don't know what they're saying about Jake.
"Not involved, and I'd be that nervous anyway I probably wouldn't be coach, I'd probably just go to the bar."

Australia's head coach is contracted through to the 2019 World Cup.
The incumbent Test XI, minus pacemen Mitchell Starc, Josh Hazlewood and Joe Mennie, have been sent back to the Sheffield Shield in an effort to rediscover form before the third Test starts next Thursday, November 24.
Selectors are expected to name a new Test squad on Sunday, with Lehmann guaranteeing it won't be an unchanged XI after five consecutive Test losses.
Adam Voges and Callum Ferguson appear the players at greatest risk of being axed, with Lehmann imploring his charges to start producing runs instead of words.

"We've talked a lot over the last few weeks, we talked a lot in Sri Lanka, and we talked a lot in South Africa. The time for talking is probably done," Lehmann said.
"We've actually got to make sure we're doing it on the ground. They prepare well, they're great trainers, they know what they need to do. It's now actually executing your plans on the ground."
