He Thinks He’s An Adult Now
That's a bit of an exaggeration but Dex is 11.5 - apparently the exact age that pushes a child (mine, at least) from tween peckishness to full on tween angst. He's a great kid. He'll be a great kid through his teen years and into adulthood. I have full faith in that. He's just entering that time when he is becoming his own person and most importantly, separating from us. Part of that separation includes thinking he knows everything and thinking we are annoying, weird, and embarrassing.
