Without knowing all of the details, I wonder if the goose was trying to flag your brother to stop his car, prehaps to prevent further damage to its mate. I’ve seen humans jump into traffic to stop cars. But my falacy here is assuming geese, or any non-primate, think like humans. I won’t argue whether or not they have emotions, but their patterns of thought may be misinterpeted by us.
For an extreme example, take the beached whales. Whale No. 1, refusing to stop and ask for directions, makes a wrong turn and gets stuck on the shore. He calls out to Whale No. 2.
“Moby! Come pull me offa this here beach!”
“Sure thing, Dick. (Whale No. 2 beaches) Damn! I ain’t got legs! Nemo! Come pull us offa this here beach!”
Whale No. 3: "Sure thing Moby. (Whale No. 3 beaches) Damn! I ain’t got legs! Hey, Grape! Come pull…(ad infinitum).
Back to the termites. (Admission of geekiness follows.)When I got home, I checked my X-Files episode guide for episode 20, “Darkness Falls”, but they were just prehistoric green cocoon-weaving mites. Non-explosive. Oh well. My first post fizzles to a stop. I probably make a better lurker.
