Amy can no longer trust her son because he sold her out to a door-to-door salesperson.
There was no denying they were home so someone had to answer the door and he volunteered. She told him to let the salesperson know that she was not available, and they were not interested. When the salesperson asked if his parents were home, Amy heard him say that she was there and then called for her to come outside. Her 21-year-old niece was there so she handled it and acted like she was his mom and informed the salesperson they were not interested. This is not the first time a salesperson has come to Amy’s door and has put her in an awkward situation, that’s why she chooses not to make herself available to them anymore.
