Five year-olds say the darnedest things. On this basis I would have to get a restraining order for my 10 year old daughter from her 5 year-old brother.
Calvin (from Calvin and Hobbes) would probably be get one from Susie's dad:
Five year-olds say the darnedest things. On this basis I would have to get a restraining order for my 10 year old daughter from her 5 year-old brother. First, I'm going to guess that your 10 year old has never threatened to "slit the throat" of your 5 year old. That's a specific threat. Not "I'm going to kill you." Secondly, you have established (again conjecture) an atmosphere where your kids feel safe in your home. That is probably not available to this father's child at the school.
Good friend of ours had their daughter (who was in 6th grade at the time) repeatedly threatened to be raped by a pretty unbalanced classmate of hers. The school's response was roughly your response. "Kids do crazy stuff." So they pulled her out.
