I walked over to Bobby, smoothing out any facial expression.
"Hello, Bobby," I said cordially, sitting next to him.
"Who are you?" he replied rudely. "I didn't say you could sit there."
I struggled to maintain self-control, fighting to keep myself from rolling my eyes or punting the damn kid out of the nearest window.
"Do you remember when your brother got punched on the jaw?" I asked, voice casual.
He got fidgety. Perfect. "Uh, yeah, why?"
I leaned closer to him, staring him unflinchingly in the eyes. "That was me." He gulped audibly, shrinking back. "Now, then. I hear you've been picking on a couple of girls in your grade."
"I, uh, I..."
"I don't need an explanation. All I wanted to tell you is that you may want to rethink the way you've been treating everyone. You don't want to end up getting someone really bad-tempered angry, do you?" He shook his head. "Good. Now, don't make me come back again, or I'll be very, very upset." He paled.

"Have a nice lunch, Bobby," I called over my shoulder as I walked away, grinning evilly to myself.
