Okay. Call me weird, but, I would have said something like this:
Me: "Okay guys, I should have thought about making sure go-carts would be available. I'm sorry. How about we all go back to the house? I'll have hubby throw some burgers on the grill. Then we will get out the 22, set up some targets and ya'll can have a contest to see who shoots the best. Winner gets $10.00"
My son: Cool!
His friends: Way cool!
Me: "Let's stop and get a gallon of ice cream on the way home.
All kids: Alright! Yeah!
See. Raising kids an't hard, if you think about it.
In LA, this'd get you thrown in jail faster and longer than stripping for the kids and buying them beer.
