Marilyn didn't ask Steve what his plans were for the day. She didn't really care; her only demands were to "not get in trouble." Of course, Steve had no intention of getting into trouble, or even leaving the house. No, it wasn't every day he had the opportunity to swap bodies with a woman. So for the day he'd be spending in Marilyn's body, he'd be staying at home. He didn't see any reason to leave. He could just sit here and do this all day.
