 There really isn't that much that can happen to us now. For God's sakes, touch wood. I wouldn't dream of touching wood. In my opinion, all those foolish old superstitions encourage disaster rather than prevent it. Well, that's a superstition in itself. I don't in the least mind being 13 at table, and I can't wait to walk under ladders. I'm afraid you'll have to until after lunch, unless I can persuade Mrs. Rothwell to set up the kitchen steps outside the dining room door.
