Sometimes, that stranger you see walking alone in a park, sipping a cup of coffee is more than just a businessman on a work break; everyone has a story.
The newly-manicured swath of flowers and green grass that sits downtown isn't just another park or another lunch spot for Larry Cutuzzi; this park exists because of his daughter. It exists because a group of terrorists decided to do something that killed her.
Lauren Grandcolas was the only Houston resident on board United Flight 93 on September 11, 2001.
"We live in a world (that's) totally different," said Cutuzzi.
Sept. 11 happens once a year. And once a year, the majority of Americans stop, reflect and pledge to never forget an attack that killed thousands of people and changed the way we travel.
Cutuzzi thinks about it daily. It changed a lot more than just the way he travels.
"I think of Lauren every day," said Cutuzzi. "I'm sure every parent who has lost a child has the same circumstance."
His daughter's life, and that of his unborn grandchild may be gone, but in the middle of downtown Houston, their memories live on.
Lauren's Garden is a gift from her family to the city. It sits in Market Square Park surrounded by skyscrapers, traffic and the hustle and bustle of the downtown Houston workforce.
And on this day, a man with a coffee cup takes it all in.
As city leaders, politicians and musicians pay tribute to those who lost their lives so many years ago, Cutuzzi smiles, shakes hands, and then quietly slips away.
You just never know who that businessman walking alone may be.
