Bob Cratchit is the only employee of Scrooge who is treated very poorly and is very underpaid. He is also father to "Tiny Tim" who is very ill. The ghost of Christmas past is the first ghost to teach Scrooge a lesson, taking him to the Cratchit home, located in Camden Town. In this home, Scrooge develops empathy after witnessng Tiny Tim and after being toasted to before Christmas dinner, even after his cruelty that causes the suffering of this family. During Dickens' era, it is noted that Camden town was in great poverty and tainted with suffering.
