Strangers. Friends.

There’s a fine line between strangers and friends. This is a chilling and beautiful reminder…

On that terrible morning, when American Airlines Flight 11 hit the North Tower of the World Trade Center, Victor Wald, 50, was working in his 84th floor office at the small brokerage firm, Avalon Partners. Like his colleagues, he raced for the exits, and scrambled down the stairs. But, having suffered from rheumatic fever as a child, he collapsed in exhaustion on the 53rd floor, as frantic workers from the building's upper floors hastily passed him by. Harry Ramos, 46, the head trader at the small investment bank, May Davis Group, who worked on the 87th floor, saw him on the stairs, and stopped. They had never met, had no friends or relatives in common. But Ramos saw Wald and said, "I won't leave you." Ramos managed to coax Wald down to the 36th floor, where they sat together as the building collapsed.
