No cows in the house, please

I woke up at 3am a few days ago and very urgently called for mommy. Repeatedly. When she woke up, I told her that cows belong OUTSIDE the house. She must have been half-asleep, because she thought it was an odd thing to say to someone at 3am. But I was imparting important information! To make my point, I lectured her for nearly an hour on where cows belong (the farm and the petting zoo) and where they do not belong (inside the house). I think she realized how critical the information was when she woke up several hours later. You can be sure of one thing -- she did not let a cow in the house!
