"Was he a scholar that lived in a house other than College, Pete?"
Sorry about the confusion and the ambiguity, InertPotato. Let me rephrase it:
DS was a KS i.e. King's Scholar and lived in College where all the King's Scholars live. So they are also known as Collegers. There are 70 Collegers at any one time and they have the letters 'KS' written after their names each time the individual is mentioned or referenced to in any Eton connotations - even long after they're dead: e.g. John Maynard Keynes KS (greatest economist of the last century whose ideas fundamentally changed economic policies of governments worldwide; or Eric Arthur Blair KS (George Orwell to you and me); or Harold Macmillan KS (Prime Minister - 'You have never had it so good') etc.
College is the original and oldest Eton house and is the only house situated inside the School itself and therefore, has many advantages e.g. next door to the famous playing fields; a few seconds' walk to College Chapel (not to be confused with School Chapel); College Hall where all Collegers dine is at your back door - the food served is said to be of the standard of a Michelin Star hotel (and I'm not going to argue about that); the Provost's and Head Master's offices are on the same corridors where your room is, as are the Admin Offices downstairs; the classrooms, theatre, swimming pool, etc. are just a stone's throw away across the road. And as far as I'm concerned, parking my car each time I visit is a breeze - wait till you go and collect your son from any of the other 24 houses during exeat or end of term holidays.
Okay, so I'm not comparing like with like but College is not like the rest of the other houses. It IS the foundation itself! But other than the aforementioned differences all else are the same - they wear the same uniform (an extra gown over for Collegers and they hate it); have the same teachers, depend on subjects obviously; play the same games and have equal access to all facilities, etc.
DS liked to visit his friends at other houses and vice versa. In fact, it was quite difficult for me to get hold of him at College even late at night because he'd be all over the Eton village and elsewhere, e.g. with his private tutor, attending a meeting of one kind or another, still on the road at 0115 hrs in a school coach returning from an away match at heavens know where, etc.
Like I said, his room at his 'house' is where he goes back to sleep and to have some privacy like doing private work. The rest of his waking hours are spent interacting with other human beings. And they tell me why it is preferable to live in a dorm with your friends rather than in your own private room. Or maybe it is - what else can you say when you don't have the money to build each boy his own room?
