"He's never away," she answered, with a toss of her curly head. "We're most always together, unless he goes to town--or up to your house," she added, as an afterthought.
Allison was about to say that Romeo had never been there before, but wisely kept silent.
"Twins are the most related of anybody," Juliet went on. "An older brother or sister may get ahead of you and be so different that you never catch up, but twins have to trot right along together. It's just the difference between tandem and double harness."
"Suppose Romeo should marry?" queried Allison, carelessly.
"I'd die," replied Juliet, firmly, her cheeks burning as with flame.
"Or suppose you married?"
"Then Romie would die," she answered, with conviction. "We've both promised not to get married and we always keep our promises to each other."
"And to other people, too?"
"Not always. Sometimes it's necessary to break a promise, or to lie, but never to each other. If Romie asks me anything I don't want to tell him, I just say 'King's X,' and if I ask him anything, he says 'it's none of your business,' and it's all right. Twins have to be square with each other."
"Don't you ever quarrel?"
"We may differ, and of course we have fought sometimes, but it doesn't last long. We can always arbitrate. Say, do you know Isabel Ross?"
"I have that pleasure. She's coming to dinner to-night, with Aunt Francesca and Miss Rose."
"Oh," said Juliet, in astonishment. "If I'd known that, I'd have dressed up more. I thought it was just us."
"It is 'just us,'" he assured her, kindly; "a very small and select party composed of our most charming neighbours, and believe me, my dear Miss Juliet, that nobody could possibly be 'dressed up more.'"
Juliet bloomed with pleasure and her eyes sparkled. "Isabel came out to see us," she continued, "and I don't think she had a good time. We showed her all our fishing rods, and let her help us make fudges, and we did stunts for her on the trapeze in the attic, and Romie told her she could have any one of our dogs, but she said she didn't want it, and she wouldn't stay to supper. I guess she thought I couldn't cook just because she can't. Romie said if I'd make another chocolate cake like the one I made the day after she was there, he'd take it up to her and show her whether I could cook or not."
"I believe he would," returned Allison, with a trace of sarcasm which Juliet entirely missed. Then he laughed at the vision of Romeo bearing the proof of his twin's culinary skill into Madame Bernard's living room.
