Class is a funny thing. A supposedly uniquely British obsession, it's very much part of the Irish landscape too.
When Ryan Tubridy announced that he was stepping down as presenter of The Late Late Show, so many of the profiles about him mentioned the fact that went to Blackrock College.
Why do we know that Brian O'Driscoll went to Blackrock but not have a clue what schools the two Keanes - Roy and Robbie - attended?

A few years ago, Stephen Ireland was widely ridiculed after photographs of his home appeared on social media.
His daughter Jessica had the kind of bedroom that many girls dream of having - all done up in pink with a Barbie theme.
The Corkman had his surname etched into the baize on his snooker table and he spent over €100,000 on an aquarium.
The self-appointed style police put the boot into the Corkman and pilloried his supposed lack of taste.
This is snobbery of the worst kind and all too common when many people comment on footballers' lives.
How often do you hear them described as overpaid? Too often to count.
How often have you heard golfer Padraig Harrington described as overpaid? But he has a net worth of over €40m, way higher than the vast majority of footballers.
Students who move from the country to Dublin tell the same story - even if they're from generations apart.
They all talk of the obsession with their Dublin contemporaries asking each other what school they went to.
One of the most interesting aspects to Ireland's rugby team is the way it's a form of social experiment.
The vast majority of the players went to expensive fee-paying schools but coach Andy Farrell is from very different stock.
He hails from the town of Wigan. Solidly working class, solidly rugby league - the most working class of sports.
At 16, Farrell was a father with his girlfriend, Coleen O'Loughlin, giving birth to Owen.
Farrell took the responsibility in his stride. He'd rise at 6am to pump iron to help build himself for rugby league, then do a day's work as an apprentice joiner, head to another training session and then head home for family time.
He was a typical north of England grafter. Someone who wouldn't look out of place propping up the bar at the Rover's Return.
Not many private schoolboys here come into contact with apprentice joiners. Pity, really. Farrell has shown they can blossom together.
We're only months away from the Olympics in Paris, marking 100 years since Ireland first competed at the Games as an independent nation.
One of the reasons to cherish the Olympics is how it transcends class barriers. Boxers from Traveller backgrounds rub shoulders with sailors, who grew up in the lap of luxury.
It's a reminder that class barriers can be knocked over.
