What is the summary of Shooting Kabul Chapter 15?

In Chapter 15, Fadi attended a Mosque with his family and the imam spoke about how terrible the terrorist attacks had been. Later, Fadi went to a toy store with his father, cousin, and uncle. While he was there, Fadi saw an aisle full of Barbie dolls which reminded him of Mariam. He was so upset that he attacked the dolls, damaging some of them so badly that his father had to pay for them. Later, Fadi learned that an ice cream truck driver called Mr. Singh had been attacked.
