My Fair Lady

My boss asked me to give feedback about people that I don't work with in Cube City. I don't know what to tell her. Performance reviews are coming up, and I want to be helpful; however, all I have for these people is high-level impressions that have nothing to do with their work performance. It doesn't seem fair to offer feedback when I have nothing to say. But, as my father would probably say, who ever said that Cube City is fair?
