The misunderstanding that occurs early in the story "The Horned Toad" by Gerald Haslam between the grandma and the narrator is generated by communication barrier.
The grandma does not speak any other language except Spanish. This was too hard for the narrator to understand. There is a lack of communication caused by language barrier between the grandma and her grandson, the narrator.
Thus, the narrator felt insecure about the presence of his grandma, who came over to live with the extended family in California.
