ICE CREAM!

One of the great things about being an adult is that you can eat ice cream with chocolate syrup for breakfast. Another great thing about being an adult is that you can deny your children the same privilege and then rub it in by eating your ice cream with chocolate syrup right in front of them, all the while telling them how good it tastes (even if it doesn't (but it always does)).

One of the great things about taunting your children in this way is that, to them, you're acting in a perfectly understandable manner. They would do the exact same thing in your position. They might get angry or cry, but it would never occur them to call you immature (unlike your no-fun grump of a wife who is so no-fun that she never eats ice cream with chocolate syrup for breakfast, even though she could (and, let's be honest, has been able to for quite a number of years)), because there is no mature or immature to them, there is only being. There is, however, not eating ice cream with chocolate syrup for breakfast and definitely eating ice cream with chocolate syrup for breakfast and that second one is you, so even if no-fun grumpy-skirt happens to be around, you win.

So there.
