Things only dads understand: the transition from cool to uncool overnight
My oldest is 11 and I swear it happened between Tuesday and Wednesday. Tuesday I was the funniest guy alive. Wednesday I embarrass him by existing in public. I walked into his classroom for volunteer day wearing my normal dad uniform (cargo shorts, dad shoes, polo shirt) and he looked at me like I'd shown up naked. My younger kids still think I'm hilarious. I'm cherishing it while it lasts because I know the expiration date is coming.
Man, I felt this in my soul. My 11 year old went from laughing at everything I say to rolling her eyes so hard I worry they'll get stuck. The switch flipped literally overnight for us too.
