General Manners:* It's usually not polite to point.

Unless you see an interesting reptile, like a turtle:

Suburban Chicago, Autumn 1963. I stand along a bank of the Des Plaines River, in the Forest Preserve, and I ask my Dad to take a picture of a turtle. See?

Or unless you see some interesting birds, like some ducks:

Erlangen, Germany, 1946. My Mom and her medical-school roommate point to some ducks swimming in a public park.

*Here, I continue the non-holiday version of the series, "Christmas Manners."
