PARK SLOPE - After the memorial ceremony held at Ground Zero ended, Park Slope residents gathered at the Joseph G. Duffy Funeral Home to mourn the lives lost on Sept. 11, 2001.

Those who work at the funeral home say they provided services for residents who lost their loved ones in the terrorist attacks 10 years ago, so they felt it important to pay tribute to their memories.

"It was a difficult time," Robert Amato, who works at the funeral home, says. "Not just for them, even for us."

Several children in attendance weren't alive at the time of the attacks. David Soto, who was born after 2001, says he learned about the event in his social studies class and felt it was important to remember those who died.
