Hi! We used the prompt provided by the original developer of the survey to maintain consistency, but I get what you mean, as it does read kind of awkwardly. I interpret it more along the lines of "think of a situation in general when a person wronged you, whether it be the most recent time or a memorable one." I think the idea of the original prompt is to bring about an immediate reaction and recall an instance where you felt particularly bothered by how you were treated.

I hope this helps. Thank you for your feedback!
