We call it life lesson's on how to deal with different types of people...and they will make great spouses or religious because they know how to cope with others. (just put it under conflict resolution for homeschooling)
A couple of rules:
1. no bad words
2. no hitting
My kids have to answer 3 questions-
a)what is your job in life:to make my little brothers and sister's happy!!!
b)KEEP YOUR HANDS TO YOURSELF!!!
c)IF YOU CAN'T SAY ANYTHING NICE DON'T SAY ANYTHING AT ALL!!!
