Letter 1 is from a jealous husband. Prudie tells him not to be jealous. He's really pathetic.
Video is from a woman who works in an office next to a belcher. Prudie says to get all those indisposed by the belcher to gang up and go see the boss. I don't believe this: she can hear a belch from another office (with a wall, not a partition, between them), and hear it over the sound of music? And dozens of others who one would expect don't share a wall with him also are so disturbed? FAKE.
Letter 2 is from a woman who was mildly abusive to her son, and is now disappointed that he isn't as loving as she would like. You damaged your child and your relationship, and apologizing now, however sincerely, just can't make him love you the way you think he should. I'd say you need to work on being a great grandmother, even if that means taking some long car trips to spend more time with his family.
Letter 3 is from someone who works for a large company she'll soon be leaving. Before she leaves she has to write an evaluation of a less-than-stellar assistant on a short-term contract, one that would allow him to stay on after. He's struggling to make ends meet as he supports his siblings. Should she lie and help him keep his job? She doesn't care at all about the company. I say: You may have just been a terrible boss. Companies don't care much about the feelings of their employees so I wouldn't worry too much about hurting the firm. If he's really hopeless, he'll be fired soon enough with or without your letter.
Letter 4 is cacapoopoo. LW works at home and is incommodée par her cleaning lady who shits a big smelly poo before leaving, every single time. Should she tell her to hold it? Prudie says: Are you crazy? I agree. Install a portapotty in the backyard and tell her it's the servants' loo.
