Public and Public

I've realised most visitors are Yanks, so I thought I would post this:

The term public school has two distinct meanings:
In the USA and Canada, elementary or secondary school supported and administered by state and local officials.
In England, Wales, Northern Ireland and some other English-speaking Commonwealth countries, a private or 'independent', fee-paying school, generally not coeducational. - Wikipedia

I am the second one (the fee-paying school alumnus).
