A woman with Down Syndrome beamed with delight when everyone on her flight joined in to sing Happy Birthday to her. 24-year-old Grace Reber, from Oklahoma, was flying to California to be part of a conference that celebrates moms of individuals with Down Syndrome and special needs. Grace has never let her condition define her, her mom, Bonnie Reber, said, as she runs her own business, GracePlace Art, which has a popular Instagram page. Though Grace was set to have a vending booth at the conference, Bonnie said she felt bad about making her daughter fly on her birthday and wanted to make things special so Grace could celebrate all day long. After she and Grace boarded the plane, Bonnie told Southwest Airlines flight attendants that it was her daughter's birthday, hoping they would give her a little attention on the flight. What followed, though, exceeded even Bonnie's expectations, as the crew took it upon themselves to ask those on the plane if they could sing Happy Birthday to Grace. Everyone on board was happy to oblige – even turning on their overhead lights to appear as if there were tens of makeshift candles. As everyone started singing, proud Bonnie recorded her daughter's reaction, with Grace beaming from ear to ear.
