My Own Worst Enemy

Someone at work asked me to fix their printer as it was a legacy from our previous owners that someone had pulled from the garbage.  The power outage reset the print servers and the device was no longer showing up properly so I set to work.  One of the fellows told me I had it set up to print through the locally connected computer but I didn’t see that as the settings.  After dicking around I was asked:

Bob: Don’t you remember what you did?
Me: Nope, not a clue.
Bob: But you seemed so confident last time.
Me: Well, I have one of four methods of dealing with it.  I’m not sure which will work.
Bob: You mean you don’t diagnose it and then fix that?
Me: No, not at all.  I guess until something works.
Bob: YOU FOOL!
Me: What?
Bob: NEVER GIVE AWAY A SECRET LIKE THAT.
Me: What are you talking about?
Bob: If you had said “yes” and said there was a technical issue, we would have never known.  Now we know you’re bumbling through it like the rest of us.
Bob #2 (there are two Bobs in the machine shop):  *nodding head* We never would have known.
Bob:  You bake a lot, so I’ll keep your secret.
Me: Thank you (?)
