Chapters 11-17

When Frankenstein invites Victor into the cave he begins telling Victor everything he has learned; light, dark, warmth, cold, hunger, thirst, and sleep. All of which he had to learn on his own, he figured out that humans are scared of him so he lived outside a families cottage, taking their food and living comfortably. But then, he notices that the family is unhappy because they have no food and is poor. Frankenstein realizes this and stops taking their food out of guilt and starts leaving wood by their door. As he keeps watching the family, he realizes that they have a way of communicating with each other "talking" and he begins to try and teach himself how to do that, it then became writing. After talking and reading and writing, he started to learn about human society and history.
Frankenstein, in my opinion started to show human characteristics. He saw himself in a reflection and realized how ugly he was and became sad, he also realized how lonely he was with nobody to be around. Also, when he started to feel guilty about taking the families food it showed he had a heart and cared and wasn't a scary monster. The monster watched the relationship between the two lovers in the cottage, and it made him lie desperate and want for Victor to accept him and not feel ashamed of him.
The monster tired of loneliness decided to introduce himself to the family, so while everyone went away for a walk he went up to the oldest one who was blind hoping that he would see his nice nature, but the rest of the family came back unexpectedly and told the monster to go away scared of how Frankenstein looked.
Being rejected from humans so many times he decided to stay away from humans. He explained to Victor that he was travelling to Geneva and on the way he tried to rescue a girl from drowning but a man who was there thought Frankenstein was trying to drown the girl and shot him. On the way he saw William Frankenstein and since he was mad at his creator Victor, he strangled William with his hands and slipped the picture of Elizabeth in Justine's pocket while she was sleeping. Trying to prove to Victor that he is lonely and will always be like that he asked for another monster to be his mate. Frankenstein promised to take his mate to South America when Victor is done creating it, and promises Victor that he doesn't have to worry about Frankenstein killing anymore.
