"Honestly, I don’t know why people think some anonymous internet know-it-all like me can force their loved (and unloved) ones to obey them."

I don't think she is going to go home and say "honey the internet lady thinks you are disgusting" I think people write to the advice columnests hoping for a secret manipulation technique. I'm sure most people who write those kind of letters are women and if you ever read a Cosmopolitan or other magaizine like that it is filled with articles teaching you "Don't say this.... say that to get what you want."

I had to stop reading those magazines since I was finding them ridiculous and a waste of money but a good one I did learn is if you know your SO loves to go bowling, and you don't want to go bowling. You don't ask what do you want to do tonight, you ask Do you want to go to the movies or to minigolf tonight. He picks one, doesn't realize he has a choice of bowling and you are happy too.

I think that is what people look for when they write those kind of letters... so the translation is "Oh wise woman, teach me your manipulation techniques so I can say one thing and he realizes the error of his ways."
