I recall, but vaguely, that I used to take my own toys apart when I was small, and this seemed to worry my parents. One day I overheard our family doctor tell them, "He only wants to know how they are put together and what makes them work, so that he can make them himself someday."

And, when I was five, my mother asked my First-Grade schoolteacher why my penmanship was so bad. She also told my mother not to worry. "Your son thinks faster than he writes."
