Be a sports commentator, not a judge: report the play, skip the verdict.

When something goes wrong we want to explain it by who the person is. That is a guess about intent, and the other person can simply deny it. What you can actually report is what happened and what it caused, such as how often, when, and which build broke. Words like never or careless invite a defence.

Read it once, then a question tests whether the trick stuck.
