You can tell alot about a person from the things they say.
Walking down the streets, over hearing snippets of people's conversations lets you peek into their lives.

                             "She's beginning to grow suspicious..."
                             "We cannot let her find out about us." 

"I think I love her."                                                                                       
"That's...great."                                                                                              

                                             "What if they really get married?"
                                             "I'll go live with Dad."

"Even the neighbour's kid got into a good high school."                                                                           
"Yes, Mother. I apologise."                                                                                                                              

              "So she really asked you out to prom?"                                                                                                                                                 
"No. She asked my hamster to be her date."
