Naheed knows that she looks different because of her hijab and felt insecure about it. When the boys were pointing at her she was used to people asking questions. Although she was used to the questioning she never liked people asking her.
Naheed doesn’t want to stand out more that she already has to, but Eliza wasn’t helping the cause. Some people already thought that Eliza was weird so then they will look to Naheed, but at the same time Eliza was her only friend.
