Houstonian still feeling survivor?s guilt decades after the attack on 9/11 while he was in NYC

On Saturday, we mark 20-years since the 9/11 terror attack, when we lost 3,000 lives on September 11th and thousands more from the injuries and health issues sustained that day, and in the cleanup that followed. Miraculously, many survived being at ground zero the day of the attack, one of them was a Houstonian visiting New York for work at the time.
