Throw him at the deep end.
Instead of 23c. 24/7 indoors go straight to a grouse moor on Day 2.
Followed by a day’s rough shooting.
On day 3 a more relaxed session of driven shooting.
Then a few days or whatever it takes to bag a Stag.
Then a go at Pike in your local burn.
In other words normal life for a Scot....he must learn that when in Rome....
