Reading Passage
It was the week of the school dance, and everyone was talking about it. Maya and Zoe, who were joined at the hip, had big plans. They were best buds since second grade and did everything together. On Monday, they hit it off with a new student named Ava. Even though she was different from them, it didn’t matter. “We’re like birds of a feather,” Maya said, smiling.
By Wednesday, the trio was busy making decorations. They were laughing till it hurt and goofing around while cutting heart shapes. On Thursday, Ava forgot her lunch, but Zoe shared hers. “That’s what a friend in need does,” she said. Later that day, Maya tripped and fell in the hallway. Ava ran to help. “I’ve got your back,” she said.
The night of the dance came fast. The three of them walked in together like a team. They danced, laughed, and even had a heart-to-heart about how happy they were to be friends. “This is the start of something great,” Zoe said. “We’re already making memories.”
