George H.W. Bush wears book socks to honor Barbara Bush's commitment to literacy

Former President George H.W. Bush paid tribute to his late wife, former first lady Barbara Bush, in a very simple way at her private funeral in Houston on Saturday: he wore socks with books on them, to honor her commitment to family literacy.

Jim McGrath, the spokesperson for the former president's post-White House years, tweeted out a picture of the socks Saturday. The funeral service, which hundreds attended, paid tribute to her life, and their 73-year-marriage. She died at the age of 92 on Tuesday.
