Passage: I was sitting on the couch in my living room when I heard a loud '' ding dong ! '' chime through the house . I got up from the couch and walked to my front door . '' Ding dong ! '' Once I was standing at the door , I raised myself up on my toes a little to be able to see out of the peephole . I saw that the person at the door was my mail delivery person . I unlocked the bolt on the door , turned the doorknob , and slowly opened the heavy wooden door and then the screen door . Once the doors were open , I cheerily greeted the mail delivery person and took the mail they handed to me . Once I had taken the mail , I then wished them a good day and I closed the door behind them as they left . Question: Where were they walking to? Option1: the couch Option2: The front door
The front door
