Two people agree to a mentoring relationship, meet several times, and it quietly stops. Neither could say what went wrong, and both feel mildly at fault.
What usually happened is that each arrived with a different understanding of what the arrangement was, and nobody said so, because the whole thing was framed as a generosity rather than an agreement.
What the senior person owes
Candour rather than encouragement. The junior person has access to encouragement everywhere. What they cannot obtain is an accurate assessment from somebody with no stake in flattering them. A mentor who only encourages has provided the abundant thing.
The specific rather than the general. Cases, situations, and what actually happened. Principles are available in books.
Confidence, held properly. The relationship depends entirely on the junior person being able to describe something they handled badly. One instance of that appearing elsewhere ends it and ends the possibility with anybody they talk to.
Honesty about the limits. If you are not going to sponsor them, say so. If your experience is twenty years out of date in some respect, say that. A mentor who lets somebody believe they have more backing than they do has done real damage while being pleasant throughout.
What the junior person owes
Preparation. Arriving with a specific situation rather than expecting the senior person to generate content. The difference between a useful hour and a wasted one is almost entirely this.
Acting on it, or saying why not. Advice repeatedly received and never used ends a relationship faster than disagreement does. Deciding against it and explaining the reasoning is entirely acceptable and is frequently the most interesting conversation available.
The unflattering version. A mentor working from a curated account is reasoning about a situation that does not exist, and their input will be worthless in proportion to how much was withheld.
Protecting the relationship publicly. Not invoking the mentor’s name to add weight to your own arguments, and not putting them in a position where their association with you costs them something they did not agree to spend.
The conversation that prevents most failures
Fifteen minutes at the start, covering four things nobody usually raises because raising them feels transactional.
What are you actually looking for — cases, introductions, a specific capability, or advocacy? Name which.
How often, and who initiates? Ambiguity here produces a relationship that decays through neither party wanting to impose.
What is confidential, and does that run both ways?
And how does this end? A stated horizon — a year, a project, a transition — removes the awkwardness of a relationship that has outlived its purpose and that neither party will close.
Where the senior person is not neutral
A mentor inside the same organization has interests, and pretending otherwise is the most common structural failure in this arrangement.
If the junior person’s best move is to leave, or to take a position the mentor would rather they did not, the mentor cannot give clean advice on it. They may be entirely honourable and they are still the wrong counsel for that particular question.
Saying so is what makes the rest of the relationship trustworthy. I am not the right person to advise you on whether to take that job, because I do not want you to. Talk to somebody outside.
Which is also the argument for having more than one, and for at least one of them being outside the organization entirely.
Ending it well
Most of these should end, and the ordinary manner of ending is that meetings become less frequent until they stop, leaving both parties with a mild sense of having failed at something.
Saying it plainly costs one sentence. This has done what it was for, and I do not think we need the standing meeting any more.
That converts the relationship into something else, usually a durable professional connection that outlasts the arrangement by decades. The version that fades produces the same connection with an unresolved residue attached.
The obligation that survives is one-directional and worth naming: the person who received this generally cannot repay it to the person who provided it. They repay it to somebody else, later, which is how the practice sustains itself in a state small enough that everybody eventually knows everybody.
