When you hear these words in your next meeting with a developer, don’t flinch; they’ll attack. Here’s what to do: Ponder out the window as if you’re in deep thought, and then look back with an inquisitive look or scratch your chin. Wait for them to follow up their declaration with more info.

… They’re listening.
