Ireland v Scotland Six Nations: Josh van der Flier loving his time with Ireland squad
Barely there a wet week and already Josh van der Flier is taking liberties. Got his own room, he has. Thinks he's the bees knees. Loves himself. Buried in a book, wouldn't look at you half the time. And if you were sharing a room with him, he wouldn't talk to you if you left the wet towel on the bed.
Time to take this clearly rampant ego-maniac to task. But then a wonderfully expressive moon-shaped grin creases his cherubic figures and the mood has gone.
He can't help himself, you see.
Give him a job and he will do it. All day. Hitting rucks. Check. Making tackles. Check. Just don't ask him to do too much at once. Not yet, anyway. Which, for someone who, in just a short few months, has made his Champions Cup debut and held his own against triple European champions, before becoming the undoubted breakthrough star for his country, is more than a little arresting.
"The focus thing is kind of helpful with rugby," he concedes.
"But it's also good to be able to multi-task in terms of defending and trying to mark who you're on, and also trying to look who's outside you, so I suppose it's probably better to be able to see loads of different things.
"Multi-tasking is definitely something I could work on.
"I'm absolutely loving the environment, loving playing and in a way, yeah, you don't want it to end, you just want to keep playing games," he enthuses.
"Obviously you want to be winning those games, it's no fun, never any fun losing really.
"So you want to be playing as many games and performing as well as you can really.
"It's all really surreal. I haven't really had a chance to sit back and look at it all. I'm just trying to take it all in."
Van der Flier, who started Ireland's 58-15 thumping of Italy at the Aviva last weekend, will be hoping to enhance his growing reputation at home to Scotland on Saturday as the Irish seek to climb the Six Nations table.
