Some people are born engineers. Their behavior dictates it from the moment they can walk, and you have to treat them accordingly.
The engineer child easily becomes obsessed with data. If something is cool, he has to know everything about it. In this hypothetical situation, we'll visit an aviation museum and look at an SR 71 blackbird.
He looks at the SR71 with mild interest. It is really kind of a boring plane compared to all the curvy and colorful ones in the building. He sees that big brother is captivated by it and makes a mental note of what it looks like. Drawing this airplane later might win him some bonus points. His interests lean more towards the shining and gleaming glass domes of the bombers. He marvels at the cramped spaces.
The SR71 is located outside the entrance. It is literally the first airplane we see. At this point we might as well just go home. The other airplanes are merely scenery to the engineer while he tries to pry as much information as possible out of mom and dad. He may note the interesting mounting methods employed by the museum to hold the airplanes from the ceiling.
Hours later, despite multiple Siri inquiries, his thirst for data on the SR-71 is still unquenched. He asks for more information and we unleash him on wikipedia. At some point, the rest of the family goes to sleep with the glow of the screen still illuminating the engineer's face. In the morning he can, and will, recite everything he recalls about the SR-71. This includes its design date, retirement date, operational tours, major design highlights, capabilities, drawbacks, flight ceiling, maximum speed, and so on.
When asked whether he wants to return to the museum to get another look at the SR-71, he doesn't reply with the excited "Yes!" that a parent might expect. Instead, the engineer child blurts out that the one at the museum is not an SR71 but in fact an A12, a nearly identical airplane, which has the following design date, retirement date, operational tours, major design highlights, capabilities, drawbacks, flight ceiling, and maximum speed.
Again, I suggest that you remain calm and ask the question again with the following modification. "Would you like to go see the A12 again?" This may or may not elicit the desired response.
