Explanation:

Gregor Samsa is the main character in Franz Kafka's novel "The Metamorphosis". After waking up one morning to find himself transformed into a bug, Gregor begins to think about his job as a traveling salesman. Even though he absolutely hates it, he is not able to quit. He dislikes waking up so early, meeting people without really bonding with them, having to worry about traveling and timetables etc. Still, since he has to pay off his parents' debts, he keeps the job he loathes:

If I didn’t hold back for my parents’ sake, I would’ve  quit ages ago. I would’ve gone to the boss and told him just  what I think from the bottom of my heart. He would’ve fallen right off his desk!
