@nprofile1q... Colleague: Hey, this thing hit an error. You know it, right? Is it broken?
Me: What was the error?
Colleague: ... I don't understand the question.
Me: Error is text. What did it say?
Colleague: Ohh. No idea. I closed it.
Me: Let me just rerun... And the error says you don't have X in the data.
Colleague: So to fix it...?
Me: Put X in the data.
