Best: It was a lesson I got as a fresh grad. I was losing sleep over stress from work. "This is just a job," an older colleague told me. In reality, he really did his job -- he was always on time, his code was impeccable, and he used cool logic to solve any problem. And yet, he was never too emotionally attached to work. He always welcomed criticism of his work. He had the demeanor of a cool-headed hitman finishing h…
Clearly he's got some issues given the reaction. However, was he informed of the bug? Was there an expectation he would fix his own mistakes? I don't work in IT/Software Engineering - I work in law. But when I find fault in other's work, it's a courtesy to let them know and give them an opportunity to address it. It's part of being a team player. I am not trying to be critical of you. It's just reading this reminded…

People can specialise in a certain area of the codebase but no one 'owns' anything. Everyone needs to respect that any change to the code is a neccesary one. The 'expert' or original coder is usually a reviewer of the changes proposed anyway so thats when they can voice opinion on whether someone has misunderstood something or not.
Bugs/Features can be worked on by anyone without ego getting in the way.
