Some years ago I had a coworker I’d befriended

She lived near me with her parents and her elderly grandfather. This was back when Vanessa L Williams became the first African-American Miss America.

We were watching her on tv, when my friend’s grandfather, who rarely spoke, said, "She looks like a nice Finnish girl."
(He was originally from Finland.)
My friend and I looked at each other and she said, "’Ukki’(Grandpa), she’s black.”
He replied, "I know she’s black too, but I can always spot another Finn."

I didn’t think about that for literally decades, until I recently saw her posted DNA results under ethnicelebs.com:

There’s a lot there, but Finnish is included. He called it.
