"Supper, children! Come on in and get washed!"

"Oh, yes, now I know. Why is sand like a boy?"
"Because they both run," answered Russ. It was easy to guess the riddle after Laddie had partly told it to him.
"Cousin Tom said lobsters run backwards," put in Violet, having heard Rose say that Laddie started his riddle backwards. "What makes lobsters go that way, Russ?"
