Raymond Thompson regretfully "oh"ed, then looked up at Isabel Smith and said earnestly, "Sister Isabel, actually, I'd prefer it if you'd mind my father's bathroom, but since you like it, I won't force you."
Raymond paused and added, "Sister Isabel, could you hurry up with your shower? I'm waiting for you.", and then reluctantly left Percy Stanton's bedroom.
Isabel waited until she was alone in the bedroom before letting out a sigh of relief. After a moment of silence, she stepped towards the bathroom.

Raymond squatted on the living room floor, propped his chin up with his hand, and thought about what to play next with his Sister Isabel.
As he was engrossed in thought, the doorbell suddenly rang.
Raymond frowned at the interruption of his train of thought, and when the doorbell rang again, he got up from the floor and slowly walked to the door. He then moved a small stool behind the door, climbed on it, and looked out through the cat's eye (door viewer).
