Panel 1: We're at John's office and see Jane Randomlady tell her young son Harold to be good for the dentist. He expresses extreme reluctance and refers to her as "Ma". Lynn used to love "Ma" for some reason.
Panel 2: Anyhow, she explains to the the man who's about to shove the sharp, scary instrunents, pointy needles, and horrifying looking-and-sounding drill into the little kid's mouth that she doesn't understand why he's behaving like this even though he flat out says he's scared.
Panel 3: John does his level best to put his mind at ease by explaining what things do because he knows that if Harold knows what to expect, he'll be a damned sight braver. First, he's got to remind himself that a small child will naturally be scared of a large, ugly man looming over him but after he crosses that hurdle, he should be all right.
Panel 4: Too bad Mommy cuts him off at the knees by reminding the kid of the pain that's got him scared in the first place.
Hypothesis: It's not just the clients who made his life Hell. Also, we'll have another week of this crap.
