His companion eyed him shrewdly.

"And the girl—where does she live?" she asked, reaching for Bob's cup.

He colored with surprise.

"The girl?" he repeated, disconcerted.

"Of course there is a girl," went on the woman.

"What makes you think so?"

"Oh, Bob, Bob! Isn't there always a girl on every young man's horizon?"

"I suppose so—generally speaking," he confessed with a laugh.

"Suppose we abandon the abstract term and come down to this girl in particular," his interrogator said.

"Why are you so sure there is one?" he hedged teasingly.
