Jack duly arrived at Paddington Station in London the following Tuesday armed with the information he had been give .... London WC5.

As he strode purposefully across the concourse he noticed a sign to the right - "WC". He immediately made his way through the door and down the stairs where he encountered a row of small doors with numbers on.

Consulting his notes quickly, he made his way to WC number 5 and banged fiercely on the door.

"Are you Neally Dunne?", he demanded.

"Yes, but there's no paper", came a small voice from inside.

"Dats no excuse for not writing to your Mother!!".

Well I guess we can't expect the country folk to know what a water closet is now can we.

Actually I knew what was behind the door marked WC long before I knew what the letters stood for. At the time, that was all I really needed to know.
