Answer:
-A small boy has to be reminded over and over not to pet strange dogs without permission.
-A pre-teen with diabetes resists being taught how to give herself insulin injections
Explanation:
A small boy has to be reminded not to pet strange dogs is likely to stem from the fact that he is quite young(has not developed all mental capacities)and wouldn't heed easily to instruction(reminding orally) and therefore be reinforced in this manner. At this stage children learn more unconsciously than consciously and so instructions are less effective. The same would likely apply to the pre-teen here.
