The colleague on the other side now

Enough regulatory careers move between a company, a vendor, and an agency that sooner or later you end up catching up with someone across a line that didn’t exist the last time you worked together. The friendship is real. The reporting line, the NDA, the agency badge are also real, and new. Neither cancels the other out, which is exactly what makes the conversation harder to get right than either a stranger at a competitor’s booth or a regulator you’ve never met before.

The friendship didn’t change; what travels safely through it did

It’s tempting to treat the new employer as the only thing that matters and go stiffly formal, or to treat the history as the only thing that matters and talk the way you always did. Both miss the actual shape of the situation: the warmth is still earned and still yours to enjoy, and a separate, more specific question — what’s actually safe to say to this particular person now — needs its own answer, decided before the conversation gets going rather than felt out in real time.

Catching up without catching anything you’ll regret

General and personal holds up fine across almost any move: the new city, the team they inherited, how the kids are doing, a shared complaint about a flight delay. What stops traveling is the specific, current, shop-talk kind the friendship used to run on — a pipeline detail, a submission timeline, an unannounced plan — and the slide from one into the other rarely feels like a decision, because it never used to be one. The short list that governs a stranger at a competitor is the same list here; the difference is that with someone you trust by habit, it takes active attention to notice you’re approaching it at all.

If the move was to the agency, a second line stacks on top

A former colleague who left for the regulator carries both complications at once: the personal history that makes candor feel natural, and the ordinary professional line around an informal regulator conversation that would apply even to a total stranger in the same role. Neither line cancels the other, and the old friendship is exactly what makes the regulator line easiest to forget in the moment — it’s worth naming to yourself, before the conversation starts, that you’re now managing both at once, not just picking up where you left off.
