Senior lawyers will occasionally ask for your view on a complex matter about which they know you are fundamentally ignorant, probably as a cruel joke or as a way for them to assert intellectual superiority over you. My advice is to preface whatever you say with "a wise man/woman once told me" and then parrot back what they just said on the subject followed by saying, “but I defer to you”. This will work perfectly the first time, with rapidly diminishing returns thereafter.
