"True," he replied, nodding.

"So I thought I'd prepare you for communicating with people who don't speak English," she continued.

"OK...," he said, wondering where this was going.

"For instance," she said, "don't give a thumbs-up to anyone from Thailand. They equate that with sticking your tongue out at them."

"Right," he said, nodding again.

"And you're basically flipping an Australian off if you show them what we consider a peace sign!", she shouted, sounding slightly angered.

"Really?!" Billy asked as he did so.

"Right!" she said, jumping back as though surprised. "Whereas in Greece, they get upset if you show them your whole hand!"

"Like this?!" he asked, raising the rest of his fingers.

"Oh!" she said, suddenly sounding overwhelmed by something.

She ran to her desk, removed something from a drawer, and ran back to stand beside him. She then shoved the paper into one hand, while seeming to massage the fingers of the other.

"Come to this address tonight," she said, "and I'll show you some GREAT things to do with this hand."

She then turned him by the shoulders, and shoved him through the door.
