Conspiracy theory of the week

I called the local laboratory to ask them to send us Lillie Langtree's lab results.
“For her medication monitoring?” the lab technician asked.
“Yeah, just like every week.”
“My mother-in-law needs to be on that stuff,” she said.
I should have let the conversation drop right there, but I didn’t. “Oh?”
“Yeah, she keeps telling anyone who will listen that Chinese people are trying to invade the West Coast.”
This is admittedly strange, even by my standards. “What?”
“By going south through Canada, no less! Is that crazy or what?!”
“That’s pretty wild,” I agreed. “If they do, I know some Chinese people in California who’ll hide me.”
“I’ll be able to blend right in—I’m Korean!”
