So I was sitting at an interview with an electronics company for a technical writer position. The interviewer asked me, "You're going to need to work a lot with timing diagrams. Do you know what those are?"
I replied that I had had no experience with them, but the previous interviewer had briefly explained the principles behind them to me, and shown me a few examples, and I felt confident that I could grasp their manipulation quickly.
"I've worked with something very analogous. My former company describes process recipes in a very similar manner..." blahblahblah, and at the end of my blurb, I said, "So I feel confident that I can grasp the principles very quickly, as there is a very close analog at my former company."
The guy paused.
"Actually, the signals aren't analog. They are digital."
PLUCK a DUCK!
ONE word, TWO meanings! Whoda thunk?!?
I responded, quite eloquently I think, "uhhh... buh... guh..."
