I found a very useful trait that the boys have inherited from Jason - their inability to lie without getting caught.
I learned early on with Jason that he couldn't even tell me the smallest white lie while looking me in the eye. He always looks away at the very moment the lie is being exposed OR he'll attempt to look me in the eye while smiling.
For example, a few years ago, shortly after I'd gotten a new car, I noticed a few small blue streaks on the corner of my back bumper. "Jason, did you scrape my car with the trashcan while you were trying to get it out of the garage?" "No, I don't know what you're talking about," said while looking down. As I got closer and repeated the question, Jason giggled while looking at me even before he tried to proclaim his innocence.
So far, it seems, the boys have inherited this very useful trait from their daddy and I'm hoping that, like their daddy, they don't outgrow it or practice overcoming it. It will come in very useful in their teenage years.
Harrison now: "Harrison, are you pooping in your pants?" "No," as he looks at the ceiling.
Harrison later: "Harrison, did you have three girls in your room last night?"
Jake now: "Jake, did you stuff the toilet with all of this toilet paper?" "No," as he tries to hide a smile and looks to the side.
Jake later: "Jake, did you put tire tracks with your truck in the neighbor's front yard?"
