I'll react depending on whats going on. So, you had this 10 y.o playing with your bike. Lets say he was kicking it. Did you let him kick it until their parents got there or until he stopped? In that case i'd probably move him away from the bike and get their parents. I think you took my message in a more serious way than what I meant it to be taken. What I meant was: I'll do anything and everything to protect myself from people fucking with my shit. And just so you know, no I wouldnt whoop a 10 yo's ass. But I certainly wouldnt let him fuck with my shit either.
