"Dave, I wish you would invite your sister and her friends to come down here. Ask those boys who were with you in the schooner."
"That would be pleasant. Thank you."
"I will try to make it interesting for them."
"Oh, I wish you would do one thing."
"What is that?"
"Tell us what you know about lighthouses."
"Well, let me think. There is one thing I could do. I have in my drawer an account of lighthouses I have written off at spare moments, just to keep me busy, you know, and I could read that."
"I think we would all like that very much."
"All right; let us plan for a visit."
"I think you have had some visitors since you have been here that you did not plan for."
