Actually, Chen Meng'er didn't take the apple out of her schoolbag. She took it out of her space. Yesterday, when she came back from Elder Liu's place, Chen Meng'er took advantage of the fact that no one was paying attention to her and took out a few fruits from her space. She mixed them into the few kinds of food that Elder Liu asked her to bring back.
For the first time, Chen Meng'er didn't dare to take too much. She was just testing to see if it would arouse the suspicion of others. However, fortunately, because Elder Liu was too high up in her family's heart, these fruits that didn't exist in their place didn't arouse their suspicion.
