Again with the 'she'. Brad chose the pony party, but he didn't want to have to pay for the other kids ponies. Do your children attend the birthday parties of their friends/classmates? Do you PAY for the pony rides/pool fees/bounce houses/gym fees, or what ever the latest kids party craze is? If your child is invited to a Chuck E. Cheese birthday party, do you expect to have to pay for your child to attend? When one throws a party, like brad chose to throw a pony party, then the 'throw-ee' pays for the other kids to attend, not the other way around. Nancy didn't 'go way over the budget', she merely told Brad, the invited children do NOT pay their own way to attend our child's birthday party. That's not the way it's done. If my grandson is having a pizza party, we certainly don't expect the other mom's to pay for their kids pizza, do you?
Yes I said she. Wasn't there testimony that he was mad about how much Nancy spent on the party? I haven't heard that a pony party was his idea. If they agreed on a birthday party budget, then they needed to plan a party to stay within that budget. But my recollection of the evidence (and I could be wrong here) is that he was mad about what she spent on the party.
