LOL - I was cracking up at the questions your son ask. I think he just likes your attention :)
Oh, believe me, I know he wants my attention! I had to get WD40 because the creaking noise his bedroom door made the 50 times he would go in and out during the day drove me insane!!
I suppose they do when heredity kicks in.
I'm thinking if it were a hand-me-down trait, it would be less inherited and more learned by example... so I should tell my husband to quit asking dumb questions in front of my son!
