RANT: School pickup politics are insane

I swear there's like a whole social hierarchy in the carpool line now. Some parents legit get upset if you're not in the "right" spot or don't know which kid belongs to which family. My 6yo just wants to get picked up and go to the park but apparently that's not how this works? Just picked him up yesterday and got the look from another dad because I wasn't standing with the "popular" parent group. We're grown men. This is ridiculous.
