“But so many words begin with the same initial,” said Patty, bewildered at the idea.

“Yes, but it’s ever so much easier than you’d think. Now listen. Wouldn’t you understand me if I said: ‘D y w t g t t g p?’”

“Say it again, please, and say it slowly.”

Sinclair repeated the letters, and Patty clapped her hands, crying: “Yes, yes, of course I understand. You mean ‘Do you want to go to the garden party?’ Now, listen to me while I answer: Y I w t g i i d r.”

“Good!” exclaimed Mabel. “You said: ‘Yes, I want to go, if it doesn’t rain.’ Oh, you are a quick pupil.”

“But those are such easy sentences,” said Patty, as she considered the matter.

“That’s the point,” said Bob, “most sentences, at least, the ones we use most, are easy. If I should meet you unexpectedly, and say H d y d? you’d know I meant How do you do? Or if I took leave, and said G b, you’d understand good-bye. Those are the simplest possible examples. Now, on the other hand, if I were to read you a long speech from the morning paper, you’d probably miss many of the long words, but that’s the other extreme. We’ve talked in initials for years, and rarely are we uncertain as to the sense, though we may sometimes skip a word here and there.”

“But what good is it?” asked Patty.

“No good at all,” admitted Bob; “but it’s fun. And after you’re used to it, you can talk that way so fast that any one listening couldn’t guess what you are saying. Sometimes when we’re riding on an omnibus, or anything like that, it’s fun to talk initials and mystify the people.”

“D y o d t?” said Patty, her eyes twinkling.
