Or something negative. Maybe you just got a job. Awesome. But you were in front of someone else. Someone who too could have gotten that job, someone who's been unsuccessful for years. And now he again has no chance. He keeps searching for a few more months, but now in huge debts, that person decides to take their life by jumping under a train. But this is only start. It gives the train driver trauma, he's no longer able to do his job that his family so much depended on. They can't afford education for their children. And things keep getting perpetually worse and worse. From 1 person, it now affects 5, which creates even bigger impact and the story could continue.

I am certainly overthinking this, but you never know.

Or maybe you just rejected mediocre artist from art school without thinking about it. You know that one.
