"Mom, he hit me!"
"Well, he hit me first!"
"I did not, I just barely pushed you because you were on my side of the seat."
"I was not, and it's my seat, too!"
"But you're always taking more than your share because you're the biggest."
"The biggest is supposed to get more!"
"Who says?"
"I'm just right, that's all."
"No you're not, and besides, you lied about who killed the goldfish."
"That was my goldfish- Grandma gave it to ME!"
"No it wasn't! You never did feed it, anyway."

And so on to infinity. Both sides citing 2000 detailed references to what was done to them, and both sides being correct. If you could see yourselves! I could write almost the same script for the Irish problem as for the Middle East problem or for the Balkan problem with a few detail changes.

Someone has to say "enough".
