Dear Prudence,
I’m the older brother of a sister "Anne," who graduated from college last June. She has always been hardworking and popular. However, she is extremely sensitive about the fact that while I went to an Ivy League school, she went to a good but less "prestigious" college than I did. No one else in my family has made an issue of this and everyone was as proud of her when she graduated as they were of me. This past weekend, while visiting my parents’ house, I was getting a book in Anne’s room and found a crumpled letter from her university stuffed in the back of her bookshelf. It was dated the day of her supposed graduation (which she walked at and we all attended) and alluded to the fact that she had not actually received a degree because she was short several credits. She has a good, very demanding job, and I am virtually positive that she never made up the credits and that neither my parents (who paid her tuition) nor her employer are aware that she doesn't have a degree. I don’t know whether to discuss it with her first or just alert my parents.
