Funny, I am far more often told how good-natured, and good-humored, I am with guests. I take great pride in my ability to effect a strong likeness to the person I'm drawing. So if one is always shifting about, turning to talk with another, etc., there's a good chance I lose the focus needed to do the job I've been hired to do, to the ultimate satisfaction of my client. At this event, though, I had rapport with virtually everyone. Two sweet, charming little girls were "rewarded" with a pencil that I gave each one. Most guests happily took my card.

Still, thanks again for the opportunity! :-)
