LAUDISI (_motions to them to come closer to him; then in a low voice and in the same mysterious manner, and stressing each syllable_). The certificate!--Of the second marriage! SIGNORA CINI (_starting back with astonishment_). What? SIGNORA NENNI (_Likewise taken aback_). What did you say? The second marriage? SIGNORA CINI. Well, in that case he was _right_. LAUDISI. Oh, documents, ladies, documents! This certificate of the second marriage, so it seems, talks as plain as day. SIGNORA NENNI. Well, then, _she_ is the lunatic. LAUDISI. Right you are! She it is! SIGNORA CINI. But I thought you said.... LAUDISI. Yes, I did say ... but this certificate of the second marriage may very well be, as Signora Frola said, a fictitious document, gotten up through the influence of Ponza's doctors and friends to pamper him in the notion that his wife was not his first wife, but another woman. SIGNORA CINI. But it's a public document. You mean to say a public document can be a fraud? LAUDISI. I mean to say--well, it has just the value that each of you chooses to give it. For instance, one could find somewhere, possibly, those letters that Signora Frola said she gets from her daughter, who lets them down in the basket in the courtyard. There are such letters, aren't there? SIGNORA CINI. Yes, of course! LAUDISI. They are documents, aren't they? Aren't letters documents? But it all depends on how you read them. Here comes Ponza, and he says they are just made up to pamper his mother-in-law in her obsession.... SIGNORA CINI. Oh, dear, dear, so then we're never sure about anything? LAUDISI. Never sure about anything? Why not at all, not at all! Let's be exact. We are sure of many things, aren't we? How many days are there in the week? Seven--Sunday, Monday, Tuesday, Wednesday.... How many months in the year are there? Twelve: January, February, March.... SIGNORA CINI. Oh, I see, you're just joking! You're just joking! (_Dina appears, breathless, in the doorway, at the rear_). DINA. Oh, Nunky, won't you please.... (_She stops at the sight of Signora Cini_). Oh, Signora Cini, you here? SIGNORA CINI. Why, I just came to make a call!... LAUDISI. ... with Signora Cenni. SIGNORA NENNI. No, my name is Nenni. LAUDISI. Oh yes, pardon me! She was anxious to make Signora Frola's acquaintance.... SIGNORA NENNI. Why, not at all! SIGNORA CINI. He has just been making fun of us! You ought to see what fools he made of us!
