Hah, amazing and thanks for sharing. I think it's mostly that you sounded like you were holding a petty grudge over some small technical thing that can make sense. Maybe he resigned because he felt overly judged?
No, he had a day drinking and absentee problem. My boss talked with him, offered him another chance, but he resigned. He really didn't like following requirements either but I think it was just a symptom of his overall problems. He was going through something and we were just a stop on his journey.
I am way less judgemental now and a lot of the comments here are making me rethink what I thought about him saying this. He had a lot of other issues and resigned after a couple of days so I guess we'll never know what he was capable of.
