[Developers] [Data-modeling] is everyone married to themselves?

[Jeff Fry]

As an aside, Jason mentioned wanting a query of schools that first 
ladies attended, but what Jason and John have described (apart from the 
problem of spousal symmetry) is a query of schools attended by people 
who were married to US presidents. This is more inclusive than what 
Jason described - it also gathers the educations of people who were 
married to a president before or after their term in office. E.g. Ronald 
Reagan was married to Jane Wyman from 1940-48, but Wyman was never a 
first lady.

This may well be an acceptable level of imprecision, but it's probably 
worth noting.

Cheers,
Jeff
