Mondrian,
With regard to 11A I assumed the plural was used as both (or more) of those involved in the greeting have to raise their hands.
Welcome to Charlies Human from RT thread 41, nearly missed your comment until I, like Mondrian, re-read RT 41. Good weather for bulb planting. Hope to hear from you this week.
Like Navigator, 22A, I first came across in my confirmation classes as it was/is part of The Creed used at Mass. (Now, probably updated into modern English usage.)
Yes, well done in Chile - a very smooth and successful rescue operation.
