it's not politics, i swear

[rone]

In a punishingly inane AP article on CNN.com, this quote stood out in its baffling nonsequiturness:

Bush wrote back to wish Miers a happy 52nd birthday, telling her that he appreciated her friendship and to "never hold back your sage advice." He ended with a postscript: "No more public scatology."

There is nothing in the rest of the article that explains this remark.  It's just... o_O.
