We put up a sign telling people that the conservatory would be closed from 1.30 for a private party. The High Tea birthday party of a wonderful 85 year old. No one believes he really is 85. He must have a portrait hidden in some attic somewhere.

Anyway, the sign prompted several people to ask for details about booking parties.

If I were cunning I'd put one up every week....
