Agreed. The “let me walk you through this” response sounds to me like “I’ll speak slowly for you, idiot.”

You’ve learned an important life lesson. When people tell you verbally they value something (e.g., honesty) sometimes they don’t.

You come up with an alternative, before you get there. Money always works. The commute, more interesting work, whatever. No need to drag your still current boss through the mud.

Here’s a better idea: If your present job is so complex you can’t explain it in a couple sentences, take a few minutes today to develop a brief, cogent job description. Consult colleagues, your HR records, the Internet and your mom if you need to.
