Patty looked up with the air of one who has received an inspiration. "I'm going to tell him the truth."
"Don't do anything so rash," pleaded the Twin.
"That is, of course, the only thing you can do," said Priscilla. "Sit down and write him a note, and I'll promise not to laugh till you get through."
Patty stood up. "I think," she said, "I'll go and see him."
"Oh, no. Write him a note. It's loads easier."
"No," said Patty, with dignity; "I think I owe him a personal explanation. Is my hair all right? If you girls reveal this to a single person before I come back, I'll not tell you a thing he says," she added as she closed the door.
Patty returned half an hour later, just as they were finally settling down to tea. She peered around the darkening room; finding only four expectant faces, she leisurely seated herself on a cushion on the floor and stretched out her hand for a steaming cup.
"What did he say? What kept you so long?"
"Oh, I stopped in the office to change my electives, and it delayed me."
"You don't mean to tell me that man made you elect astronomy?" Priscilla asked indignantly.
