We all have playful names for our Southern grandmothers, and Texas natives Jenna Bush Hager and Barbara Bush are no exception. The two successful businesswomen may be out of the house now – but the words of wisdom from their grandmother, Barbara Bush, guide their everyday etiquette. "She just like her grandchildren to be well-behaved," said younger Barbara, namesake to her famous grandmother. The twins refer to the former First Lady as "The Enforcer" for her practical approach to Southern etiquette, which includes Barbara Bush's occasional "biting humor" and quick-to-act spirit. We gave the girls a few etiquette scenarios and asked, "What would the Enforcer do?" From everything on what to do if a young guest shows up to a wedding in white to handling guests that show up a little too fashionably late, take a peek into Jenna and Barbara's advice on handling etiquette snafus and how they think their sophisticated grandmother would handle the situation.
