Once I had a colleague who likes to pick fight with people.
During my job interview, I sat next to his table doing the typing test. He told me that he had "gaduh" with almost everyone in the company before. It's his way to "get to know" a person.
Weird. But there are all sorts of weird people in this world. Some would pick fight for power, glory, status or ego. That, I can understand. But I really don't know what to say about people like him. Purposely picking fight for nothing. Or maybe he have a hidden agenda of his own.
