"And you can't really cover people critically that you're friends with"

This quote by Kurt Loder suggests that it is hard to objectively review somebody if you are pals with them. This is because when you are good friends with someone, you are most likely to be biased in your viewpoint of them. You may be most likely to neglect their defects and errors, or to give them the benefit of the doubt. Additionally, you may be more likely to be influenced by their opinion of themselves, rather than forming your own opinion. This can make it difficult to supply a truthful and precise evaluation of their work or habits. Eventually, it is important to be aware of the potential for predisposition when critiquing somebody you are friends with, and to aim to be as unbiased as possible.
