After Mondays deadly explosions at the Boston Marathon cast a pall over Conner Masons 7th birthday celebration, the Mason family reportedly realized that each of their birthdays were now tainted by a national tragedy. Our youngest daughters birthday is September 11, Julies is on the Virginia Tech anniversary, Laurens falls on the Aurora shooting, and my husbands is on the Newtown massacre, said Anne Mason, 39, local mother of five children whose own birthday is April 20the anniversary of the Columbine shooting. And actually, now that I think of it, my father was born on January 8, which was the day of the Tuscon massacre, and our dog Howies birthday was November 5, 2009, the exact same day as the Fort Hood attack. I think the only person in the family who wasnt born on the day of a tragedy is my youngest son Eric. Sources added that Mason was dismayed to learn shortly thereafter that Erics July 7 birthday actually coincided with the London bus bombing.
