Chapter 2 places an emphasis on the significance of the nonverbal communication through the example of the Nicaraguan children. In an attempt to educate deaf children, the Nicaraguan government brought all the deaf children from remote places in one place and soon those children started communicating with each other through the signs and gestures they have used to communicate. They have established their own new language, the Nicaraguan sign language. Through collaboration with other deaf children, they have established this language. 

This editorial cartoon defines the role of non verbal communication, as an example of a peacock non verbally calling the waiter to the table. The peacock is unintentionally grabbing the attention of other dinners, as we can see them looking over their shoulders. 

I have been through a similar situation when I was in the train and nearing my stop, I changed my spot and sat next to the door. I felt that as if I had unintentionally nonverbally signaled that I preferred to sit elsewhere to the other passenger that I was seated beside. Perhaps after a short period of time, they have realized that my intention was only to move closer to the exit.
