“The more I saw of them, the greater became my desire to claim their protection and kindness; my heart yearned to be known and loved by these amiable creatures; to see their sweet looks directed towards me with affection was the utmost limit of my ambition. I dared not think that they would turn them from me with disdain and horror.”
– Mary Shelley
Frankenstein, Chapter 15. The monster on the love and kindness Felix and Agatha show towards each other, and on his own sense of isolation and desire to be loved.
