As a sysadmin, you probably have a number of areas of responsibility. Imagine a time in your career when you had the least amount of sleep, and still tried your hardest to keep everything together. Then you meet someone who gives you the feedback that they enjoyed talking to you, but they noticed that one of those areas is not quite as buttoned up as it should be. Presumably you take that feedback to heart and fix it as quickly as the circumstances allow. 6+ years later, that person goes on HN and takes you through the dirt. Would that seem reasonable to you?
