Danny Willett set a testing clubhouse target in the weather-affected Open Championship on Friday, then revealed he was soon brought back to earth by his mother.
Willett is 41 under par for his last 10 rounds on the Old Course at St Andrews after adding a 69 to his opening 66 to finish nine under par, two shots ahead of Scotland's Marc Warren and former Masters champions Zach Johnson and Adam Scott.
But while the vicar's son from Sheffield is rightly entertaining thoughts of becoming the first English winner of the Open since Nick Faldo in 1992, his mother Elizabeth kept Willett's feet planted firmly on the ground.
"I just had a text message off my mum saying well done, you've made the cut," Willett told his post-round press conference.
"I'm sure there will be a few messages, I can feel my phone buzzing a little bit right now. But it might be a case tonight of turning the phone off and having a little bit of quiet time."
After play was suspended for more than three hours due to torrential rain flooding the course, Willett carded birdies on the second, fifth and ninth to reach the turn in 33, before another birdie on the 10th gave him a three-shot lead as Johnson dropped shots on the 11th and 12th.

Three-putt bogeys on the 15th and 17th cut the gap to a single shot, but Willett took advantage of the downwind 18th to drive to the edge of the green and pitched to eight feet for a closing birdie.
"I looked at the leaderboard on 11 and knew we were three in front," added Willett, whose best finish in a major is a share of 15th at Muirfield in 2013.
"It's a childhood dream and looking up there it's still a little bit surreal, but something I'm going to have to get used to, otherwise no point in being up there.
"You can't really put it out of your mind but it's pretty cool. Leading the Open is what you dream about. For Brits especially it's the major you want to win and here at the Home of Golf it's a little bit more special."
Willett won the English Amateur title in 2007 and defeated Rory McIlroy in the first round of the Amateur Championship the same year, racing five up after six holes before eventually sealing victory on the 17th.
And later that year he and McIlroy were on the same team in the Walker Cup as Great Britain and Ireland lost out at Royal County Down to an American side featuring Rickie Fowler, Billy Horschel, Dustin Johnson and Webb Simpson.
Willett, 27, claimed his second European Tour title in the Nedbank Challenge in South Africa last December, finishing with rounds of 65 and 66 to overturn a five-shot deficit to former world number one Luke Donald, and also reached the semi-finals of the WGC-Cadillac Match Play in San Francisco in May - losing to one of his playing partners at St Andrews, American Gary Woodland.
Warren matched Willett's 69 to boost Scottish hopes of a first home winner since Paul Lawrie, the 1999 champion among the late starters after an opening 66.
"I'm delighted with that," said Warren, who carded a closing 64 to finish fourth in the Scottish Open at Gullane on Sunday. "It was a long morning.
"I had just started my warm up in the rain and the good news came in it was going to be delayed. When we did tee off it was certainly much drier and it was just the wind we had to battle.
"The weekend of the Open at St Andrews does not get much better. The game is in good shape, I'll give it my best and see what happens."
South Africa's Jaco van Zyl hit the opening tee shot of the day at 6:32am and had a three-foot putt for birdie before play was suspended.
"They tried to squeegee the green but water was rising quicker than they could get it away," Van Zyl said. "We had the option to putt out but we all stopped, the hole was literally full with water."
The lengthy delay meant the last group on Friday was scheduled to tee off at 7:27pm, meaning the round would not be completed on schedule.
But chief executive Peter Dawson said the R&A would not employ a two-tee start, which was implemented for the first time in Open history at Hoylake last year due to a bad weather forecast for Saturday.
"We do have the ability to go into Monday (the last time that happened was at Lytham in 1988), but we certainly hope not to," Dawson said.
