What is your (or your child's) oldest personality trait?

I am sure that my daughter won’t be into peekaboo like she is today when she’s 20. But I do wonder if any of her traits she has now will stick with her.

I have a nephew that was obsessed with cameras when he was just barely over a year old. He’s only six and still really into it. I wonder if as an adult, he’ll be a photographer and everyone will remember how he used to grab random cameras off tables and snap pictures and when people were going through their pictures that evening, they’d wonder why they had so many pictures of feet and bellies.

Are there any personality traits that you, your children or anyone you knew as a kid had for a very long time? Please share!
