Well, that's it has finally come to the point where I do not understand anything about what my eldest lad studies for mathematics particularly with regard to what he will be studying next year for his MSc at Durham.  I will keep my mathematics stuff up to A level and Further Maths standard just to keep the old brain ticking over but that is it. Songwriting, jazz harmonica, geology, botany, birdwatching, history Bahai studies and trying to keep being a good husband and bloke  are the only interests for me from now on.

The lad is on his own: hooray! Goodness, he is only going to be 20 miles up the flaming road!
