| pause, think like an engineer, design a solution, review the possibilities, make up an answer and be willing to be corrected on the spot with a flattering apology like "wow, you know more than I do." |
| Say "I've forgotten, let me get back to you on that." Then get depressed, go to the library, research on the internet, don't sleep, become and expert over night. |
| Say "I am not familiar with that detail, but I will be shortly." |
| Say "I am not an expert, but here is what I think." |
| Find a starting point, and present it as the answer. |
