Secondary from Ohio

Yeah, I got it, but the question is stumping me...

It says something about how they value diversity and cultural awareness and then ask you to recount a time when you were "culturally competent." It doesn't sound that bad at first, but I am really struggling to come up with a meaningful situation, being that I am a typical suburban white girl. It also seems a little vague to me...if anyone else has any insight into this question or ideas of topics, please post. Hope that helps.
