Why was Miss Sullivan taken out through the window one day? Explain that happening to her.

Helen locked Miss Sullivan in her room and hid the key. Her father had to climb a ladder and assist Miss Sullivan in leaving the room through the window.

After my teacher, Miss Sullivan, came to me, I sought an early opportunity to lock her in her room. I went upstairs with something which my mother made me understand I was to give to Miss Sullivan; but no sooner had I given it to her than I slammed the door to, locked it, and hid the key under the wardrobe in the hall. I could not be induced to tell where the key was. My father was obliged to get a ladder and take Miss Sullivan out through the window—much to my delight. Months after I produced the key.
