This silly, three-fold use of the informal "du"
I can certainly attest to the quality of the advice, but I don't accept this idiotic and brazen use of the informal "du" (you) like eighth graders would, from a young whippersnapper 60 years younger than me. It's rude and presumptuous. Well, I was socialized in a time when different norms and customs prevailed. May I address you formally from now on...?
