I was only half joking frosty - While i dont suggest you actively play them off against one another, parents who are already antagonistic to one another are distinctly more likely to be generous to you to try and buy your favour - even if you dont encourage it.
Sorry to hear that. I have had friends who divorced in elementary school. It depends. Sometimes divorce has a good effect on the kid. The other time, it can have a bad affect. For example, if the parents argue a lot, divorce could be a good thing for kids.
