"Aunt Helen said we might see each other again some day. Do you suppose they will come back and will be nice to us and let us go up there sometimes?"
"We cannot say. I do not look into the future to find such possibilities, Nannie. You must not build too many air-castles."
"Oh, but I like to," replied Nan. "It's lots of fun to do it and if they don't amount to anything I've had the fun of the building and nobody's hurt when they tumble down."
"In that case I suppose it doesn't make much difference, and when one is naturally a castle-builder it is hard to give up the habit."
"It isn't as bad as sucking one's fingers as Jean does, for it doesn't put my mouth out of shape; it only amuses me and I often forget my castles an hour after they are ten stories high. I suppose I am not to tell the children about Aunt Helen."
"I think I wouldn't yet."
"No," said Nan with a mature air. "I think it's best not. They mightn't understand. Besides, as she isn't a polywog nor a newly hatched bird, Mary Lee wouldn't be very much interested in her."
