The debugger is a relatively simple environment: you have a program, you have inputs, and one of these leads to weird behavior. When you encounter people, they might be in a bad mood for a thousand reasons you can't know about and that you can't inspect like you can in "computer + program + data", leash out at you (verbally) for no discernable reason at all (and that they themselves may not even be aware of) When you never learned about that messiness of a system as complex as people, it can feel arbitrary and hostile. If you're the type who needs method and order to feel safe, computers are wonderful, people much less so.
