Repairing the relationship may take a different action from repairing the object.

Replacing a broken thing settles the material question and can leave the other one completely untouched. What hurt was often the carelessness, or being told late, or the sense that it did not matter much to you. Paying quickly can even work as a way of closing the conversation before it starts. Two repairs are needed, and only one of them is available for money.

Say the sentence as well as covering the cost: I was careless with something of yours, I am sorry, and I should have told you sooner. Ask what would make it right rather than deciding on their behalf.
