It wouldn't be quite right to say Grandpa didn't talk much. He talked plenty about the weather and college sports. But aside from those topics, he didn't talk much.
He'd occasionally talk about his time in the Air Force, or his work at SRP, the local electric company.
He only ever asked me about my work once. He knew I was a programmer, and he asked if people still use COBOL. I told him that it's kind of a niche language now but it's still used some places.
He retired from SRP in the mid-'80s; I picture him using a terminal connected to a mainframe. He was oldschool enough that he'd heard of FORTRAN but not C.
It was a short conversation but hey, I guess Grandpa was the first programmer in the family. How 'bout that.
