Is driving a bus not involving dealing with people?

Yesterday, I happened to run into a former colleague while waiting in line for a meal. He’s a very easygoing person. When we worked together, he wasn’t very talkative. I asked him where he’s working now, and he said he’s driving a bus. I was very surprised at the time.
It’s not that driving a bus is a bad job, but I was surprised he chose this line of work. His reason was: “I don’t like dealing with people. Driving a bus, even though I come into contact with countless people every day, I don’t have to interact with them. I just need to run my route well.”
People come and go, but there’s no need for deep connections.
Meet often, but no need to please.
This statement kept echoing in my mind for a long time. I suddenly realized that he lives very comfortably and transparently, cutting out all unnecessary social interactions, with no more workplace competition, internal conflicts, or anxiety about promotions and raises.
We are always taught to be extroverted, to learn how to communicate with others, and to socialize upwardly.
But we might overlook the most suitable way of living for ourselves. Sometimes, simply living a peaceful life and enjoying our small days is also a form of top-tier happiness.
