True Lies

My twin sister and I were born with a rare genetic defect, which means I can only tell the truth and she can only lie.

She says I’m making it up, of course.

The funny thing is, because we never have perfect information, I often speak a truth that turns out to be false, and she lies in a way that’s actually true.

“That’s not funny,” she says. As she would.

“I was just explaining…”

“Stop it,” she growls. “I’m the one who tells the truth. You’re the one who lies.”

Maybe she’s right. Honestly, it’s quite hard to tell.
