Younger Son passed his exams and is now a fully qualified diving instructor (quite fortunate as he's about to set up a project that will involve teaching people to dive). He was very stressed about the weekend in spite of all our assurances that he'd be fine so there's huge relief all around.
He took Husband diving when we visited them in Ibiza a couple of years ago and he was a very good instructor then so we knew he'd do well but this morning he did have to dive in 20 m of very cold water in a quarry in the middle of England and that must have been a bit unpleasant.
Anyway now he's home and he's given up his job so he can clear the dining room of all his junk (he was working from home and spread himself across the table and floor)! Hip hip hooray!
