What's He Doing in There?

He went where no Martian ever went before--but would he come out--or had he gone for good?ExcerptThe Professor was congratulating Earth's first visitor from another planet on his wisdom in getting in touch with a cultural anthropologist before contacting any other scientists (or governments, God forbid!), and in learning English from radio and TV before landing from his orbit-parked rocket, when the Martian stood up and said hesitantly, "Excuse me, please, but where is it?"That baffled the Professor and the Martian seemed to grow anxious--at least his long mouth curved upward, and he had earlier explained that it curling downward was his smile--and he repeated, "Please, where is it?"He was surprisingly humanoid in most respects, but his complexion was textured so like the rich dark armchair he'd just been occupying that the Professor's pin-striped gray suit, which he had eagerly consented to wear, seemed an arbitrary interruption between him and the chair--a sort of Mother Hubbard dress on a phantom conjured from its leather.The Professor's Wife, always a perceptive hostess, came to her husband's rescue by saying with equal rapidity, "Top of the stairs, end of the hall, last door."The Martian's mouth curled happily downward and he said, "Thank you very much," and was off.Comprehension burst on the Professor. He caught up with his guest at the foot of the stairs."Here, I'll show you the way," he said."No, I can find it myself, thank you," the Martian assured him.
