Cows

I forgive but I do not forget.

The wife is magnanimous, really. It shouldn't come as a surprise that he strayed. Cows which stray ought to die. What's more old cows who stray to eat young grass. If you are an old cow, admit you are an old cow. Do what old cows should do and set an example to your young cows. Don't eat grass then say you regret eating. We all know you are an old and greedy cow. After all, if cows don't eat grass, what else can they eat?

So girls, you know now that if you marry a rich guy, ensure he is a carnivore. At least he won't eat grass.
