Question

describe two incidence that show helen keller was very mysterious

Answer 1

The two incidents that show Helen was mischievous as a child are as follows.
Helen and Martha Washington were united by their great love for mischief. Once the two children were seated on the veranda steps one hot July afternoon and cutting out paper dolls. But they soon wearied of that amusement and after cutting up shoestrings and clipping all the leaves off the honeysuckle within reach, Helen turned her attention to Martha's corkscrews, the distinctive curls on people of African American descent. Martha had objected at first but then she submitted. Martha would have snipped off Helen's curls too if her mother had not interfered. 
The second incident was when she found a key to the pantry and proceeded to lock her mother in. Her mother was obliged to remain in that room for three hours as the servants were in the detached part of the house and no one answered to her pounding on the door. Helen had been sitting outside on the porch steps all along and laughed away with glee. This happened to be the naughtiest prank of hers.
