Answer:
The metaphor "short cut homewards across the swamp" refers to selecting a riskier or more hazardous route in favor of one that is simpler or quicker. This metaphor can be used to illustrate a character's tendency to make hasty decisions that could wind up costing them later on.
This metaphor applies to Tom's personality and implies that he is reckless and impulsive. He likes to take the simple route and doesn't always consider all the options. Tom can be someone who disregards the potential repercussions of his choices and is prepared to take chances in order to achieve his goals.
It's crucial to remember that this does not necessarily make Tom a horrible person; rather, it just makes him an imperfect person with room for improvement. Characters in literature frequently have defects that they must get beyond in order to improve. Readers will find them more engaging and relatable as a result.
