Answer:
Mrs. Robertson's note to Maria Elisa really helps her confidence and relieves her stress at thinking the teacher no longer likes her.
Explanation:
Maria Elisa is poor but she wants to give her favorite teacher a nice gift, just like everyone else in class. However, unlike most people from her class, she can't afford it. She feels very sad about the fact that her mom picked out a pair of stockings to give to Mrs. Robertson and she feels ashamed of having to give it to her, which is why she throws the gift in garbage. However, Mrs. Robertson leaves Maria Elisa a note thanking her for the gift because it's very thoughtful (turns out Mrs. Robertson often tears her stockings).
