Unfortunately he has done that stupid, arrogant thing some men do: he's named his son after himself, so the whole of the poor kid's life he's doomed to be 'Ronnie Jr'.
Drives me mad, even more than those who give their children daft names.
It may well be 'fairly common around the world', but it's still stupid and arrogant. Would you want to be Jim Bloggs Jr all your life? Or Jim Bloggs III ?
I think that the second is a bit of a necessary evil but once you get to the III - the Third - then it sounds great and bestows prestige and social cachet.
Having been "Wee Jim" for many many years because my late father was "Big Jim", this really doesn't feel like something I could even begin to get bothered about.
