Yes, this is a true story.

Now, I'll add that my aunt and her boyfriend have been friends for years-- his late wife was a good friend. So he wasn't just a random neighborhood guy. And I think she did put on a bathing suit rather than sunbathing COMPLETELY nude, at first.

The amazing thing is that a blonde woman in southern California managed to be vitamin D deficient! Nude sunbathing happens around these parts all the time, but not vitamin D deficiency.
