Ode (or 'oad or owed even) to the generation gap (and slang gap)

UPDATE:Snopes has commentary answering the questions:
- Was this question-and-answer exchange published in a newspaper's advice column?
- Did the question come from a submission received by the columnist (rather than being something she made up herself)?
- Was the letter on the level, or did the submitter simply fabricate a narrative for humor's sake?
The first two are definitely true.
