At least 2,500 people went to pay their respects to former first lady Barbara Bush, walking past her rose-covered, silver casket inside a Houston area church at her public viewing on Friday.\nThe former first lady, age 92, passed away on Tuesday after declining further medical treatment.\nABC News reports that mourners waited in line to walk past in a steady stream of groups of about 10 to 15 at a time at the viewing held at St. Martin’s Episcopal Church in Houston, Texas, where the couple worshipped at for many years. The viewing began at noon local time and ends at midnight. Security screenings for those who visited took place at nearby Second Baptist Church, and hundreds of people stood in line early before the viewing. A Secret Service agent stood on either side of her casket standing watch as people took a moment to bow their heads or make the sign of the cross.\nPresident George H.W. Bush surprised mourners by deciding at the last minute to greet some of them as they came to say a final goodbye to the widely admired woman, according to a People report. He stayed beside his late wife’s casket sitting in a wheelchair, and although the occasion was somber, Bush took joy in greeting small children who arrived with their parents at the viewing. Altogether, he accepted condolences, shaking hands for about 15 minutes.\n\nFormer President @GeorgeHWBush with his daughter Doro paying his respects to his wife of 73 years, the amazing Barbara Bush, and greeting well-wishers there at St. Martin's Church today. pic.twitter.com/5Kwn0U9k25\n— Jim McGrath (@jgm41) April 20, 2018\n\nOn her final day, the United States’ 41st president held his wife of 73 years’ hand as she slipped out of life.\nOn Friday, many women who attended the viewing wore blue, which was the first lady’s favorite color, and they donned pearls, which she often wore around her neck.\nMrs. Bush’s funeral, scheduled for Saturday, will host many notable guests, including former presidents and first ladies Bill and Hillary Clinton, as well Barack and Michelle Obama.
