Chapter XV (15) of Mary Shelley's Frankenstein tells of the creature's meeting with De Lacey. De Lacey, the father of Felix and Agatha (referred to as "old man"), is blind. After months of watching the family, the creature wishes to introduce himself to the family. Given his past experience with mankind, the creature finds this family very different. They are loving, comforting, and accepting (or so he believes). Thinking that he should first introduce himself to the patriarch, given his blindness will insure the creature is not judged upon his appearance, the creature times his visit after Felix and Agatha have left.
The creature enters into the cottage seeking rest. De Lacey warmly welcomes him. Asking of his history, De Lacey listens as the creature speaks of his quest to introduce himself to his "friends." De Lacey listens, reassuring the creature that all will be fine given that "the hearts of men, when unprejudiced by any obvious self-interest, are full of brotherly love and charity."
As the creature continues to speak with De Lacey, the old man comes to find out that it is his family the creature wishes to befriend. Unfortunately, Felix and Agatha return home. As the creature grabs onto the old man for security, Felix attacks the creature and chases him from the cottage. Later, upon his return to the cottage, the creature comes to find out the De Lacey's are leaving given Felix believes that "the life of my father is in the greatest danger." Again, shunned by mankind, the creature goes on to find Victor and begin his revenge against him.
