Hm, that was a good question. Her idea of a smile wasn't exactly one that communicated the right stuff. Maybe it was another direction she needed.

Vinnie put his thinking face on, idly tapping his chin with her sign that he was currently forgetting to return to her. "Well, you could... work on your body language, maybe. Yeah." There were tons of Pokemon with not much of a face to speak of, but they still managed to convey their feelings with how they acted. They had to get through to their trainers somehow.

That sounded like the right sort of advice. And thus he began to elaborate: "So, if you're happy, act real gung-ho an'excited, that stuff. Be in-your-face about it. And if you're not happy at someone, then punch them."

The best advice.
