I think there’s more to this story, ex: dad is an mma fighter. (doubtful with that beer-belly of his, but still. The teacher has NO idea what’s going on. If this was in the states, it’s also likely CPS received a call from the school and they’ll be knocking on the door soon. They showed up at my house when I with my ex, when the boy had a few scratches on him from playing in the woods. I’m going to stop now though, otherwise I might get into some extended rant about how public schools need to mind their own fucking business and quit telling people how to raise their kids, and how you’re wrong because they disagree with something. My parent/s didn’t tell me to go stand in a corner when I got mouthy, nor did they “kid-proof” anything. “hey dad” “is the burner still hot?”, “I don’t know, touch it an find out”. As kids, we played rough, got dirty, got in fights, got hurt, and started over the next day. Anyways, yeah, teachers need to stay the fuck out of it…like Coach, who would let someone “win” a fight before he ever said anything or broke it up.
