The age is 9, by the way

If you’re wondering at what age kids start to philosophize about how it’s possible for an adult to be born yesterday and still be older than they are, I believe it is around nine years old.

My nine-year-old stepdaughter — who would ask me to remind you that she is turning 10 in less than a month — has started demonstrating such notions, emerging in the form of this question (asked in utter shock): “How did you know that?”

Some examples from the past month:

9 year old (asking me a trivia question): What does ‘com’ stand for in ‘dot com’?
Me (a child of the Internet generation): Commercial
9 year old: How did you know that?

9 year old (listening to music): Who’s this song by?
Me (a teenager when “Complicated” came out): Avril Lavigne
9 year old: How did you know that?

9 year old (another trivia question, chosen specifically to stump me): Who was Canada’s first Prime Minister?
Me (a former graduate of elementary school): Sir John A. MacDonald
9 year old: How did you know that?

Indeed, it would appear that our little gem has crossed over, and her father and I have officially been demoted from all-knowing to chauffeur/maid/bank teller status.
