“Very much. It’s eerie, though, to see how much she looks like Sidney. When you are with her for a while you do seem to see that she is different.”

“A different personality altogether,” airily stated Caroline. “It’s funny, though. She even walks like Sidney,—that light springy way, awfully independent, you know, with her chin up. But Shirley seems more interested in everything than Sidney will let herself be.”

“Sidney thinks that it is not ‘good form’ to show surprise at anything. It is new to Shirley, too. Then she isn’t as stand-offish as Sidney was when she first came here. It certainly is going to be fun to watch the differences and to tell them apart. The uniform, too, makes it worse. If they only could dress differently!”

“Sidney will have something on tomorrow, Betty,” said Madge, “depend upon it, girls, that will let her friends know which is which!”

“Yes,” replied Betty, “and poor old Sidney is thinking right now that she would like to leave and go to some other school.”

“Suppose she did!” cried Caroline.

“No,” said Betty, “I think that I know Sidney well enough to say that she will stick it out and not be driven away. She may want to go, and hate it like everything to have some one look like her very twin, but she will stay, for pride’s sake if for nothing else. And nobody will know how she hates it, either.”

“Oh, I don’t know. The Double Three will know it.”

“She may say something at first, when she is so surprised. But nobody will be sure. Maybe she will not care as much as I think she will. But I think that it would be something of a shock to any one, and especially to Sidney.”

The girls agreed that having a double who wasn’t your twin would scarcely be desirable. Still, Shirley Harcourt was a very attractive girl.
