Love the disassembly stories- my DS is also a lover of taking things apart. In fact, one of his favorite things to do when he visits grandma and grandpa is to visit the dump, so he can bring home a few treasures to take apart. Not kidding. Sometimes they bring home more than they drop off.

Going along with the thread, when your DS loves to visit the orthodontist, because they are patient and explain all the machines and gadgets (and his older sister is the one who actually has the appointment!).

When your DD spends all of preschool "parents' night" hiding under the table reading "Heidi."

When your DD finally finds her people, at the uber-nerdy science olympiad tournaments.

When your DS has to bring in a celebrity photo for art class portrait drawing, and he chooses the designer/inventor of minecraft (still can't remember his real name....).

When your DD makes a pretty good representation of a Monty Python character for her Halloween costume, and none of the kids have any idea who she is (but the teachers do).

When your DS does the weekly math challenge in his head on the way home the day it is assigned.
