It was my unalloyed pleasure.

I think Simon doing his A level and having decided on a career would work perfectly. It doesn't matter that their ages are vague, they are teens and this is why they sound like their younger selves and - at times - like old people. It's period of huge transformation in one's body and mind and this sort of double-vision is very realistic and endearing to readers. :-D

As for the Welsh, it didn't bother me a bit, I was just carrying on our old discussion. The way you use it is perfectly good.

If I had any at making sound files I's send it to you, but alas, I'm still a CD sort of person. Sorry.
