I said: “Helena knows a good deal; but she doesn’t know which of us is the oldest of the two.”
Mr. put in another question: “Do you know?”
“No more than Helena does.”
Mrs. said: “Don’t you keep birthdays?”
I said: “Yes; we keep both our birthdays on the same day.”
“On what day?”
“The first day of the New Year.”
Mr. tried again: “You can’t possibly be twins?”
“I don’t know.”
“Perhaps Helena knows?”
