When your kid's coach or parent makes a post in one of the 37 apps used to track your kids activities and is very specific on how to respond. Something like, "If your kid doesn't want to play soccer this year, let me know here" or "like this post if you are in this year". and then some dumbass posts, "Adelynny is in, so excited!!!" which sets off everyone else to do the exact opposite of what the coach says to do.
Happens every time and drives me bonkers.
