You might want to hold onto your tot's carefully printed wish list this holiday. Send it to the post office and it might be shredded.

A U.S. Postal Service spokeswoman told Staten Island Live that's the official recommendation from the USPS for offices not participating in the revived Operation Santa program (which almost died entirely earlier this year). Postal officials have been responding to kids since 1912, getting help from local organizations since 1940 to keep up with the huge influx every holiday.

With enhanced privacy regulations for the volunteers, the list of participating offices on the USPS site is woefully short and missing dozens of states. The letters are being shredded to protect children's privacy and keep the letters "out of the wrong hands." It sounds like there will be a lot of paper to be recycled.

They'll have to manage the shredding between their other duties. The post office expects 97 million customers during the holidays plus 41 million shipping online via usps.com. Some 30 million pounds of mail will be sent overseas, including war zones.
