Every morning, Josh Cyganik gives Leonard Bullock a smile and a wave as he walks past the 75-year-old man's house on his way to work.
For four consecutive years, the 35-year-old track inspector for the Union Pacific Railroad has nodded to the Pendleton, Oregon, resident, who sits on his porch all day long, but not once has he ever said a word to the man.
Last month, he finally broke his silence.
As Cyganik stepped out to the curb to fill a garbage can, he overheard two teenage boys walking past Bullock's house yell, "Look at this crappy house. They just need to burn it down!"
As Cyganik glanced over, he saw Bullock with his head down.
"I couldn't believe what those kids had said," Cyganik told CBS News. "It was Leonard, this elderly, old man, who never hurt anybody a day in his life -- sits there all day long."
