Michael Laurich these kids are childish enough to hate each other over something so trivial they forgot about it
having recently been a stupid kid i can say from experience that kids put very little thought into anything and that those same kids likely uttered racial slurs and assaulted each other at some point
If their mischief was enough to cause me annoyance, then the value of my relationship with them is severely diminished -- the friendship becomes expendable.
Children, being basically retarded however, would happily continue to play with someone who rubs boogers on them and steals their toys.
