‘A storm blew through here and I thought it was a car accident around the corner,’ he said. ‘I haven’t heard a thing.’ 
Brennaman said he has exchanged greetings and small talk with the husband and wife but couldn’t recall their names and didn’t know them personally.
‘I wave at him from time to time. He’s always working in his yard,’ he said.
