Can I get a trade-in?

So we're on our own for the weekend, Arabella and I, and things are starting a gradual slide into madness. Yesterday turned out alright after an inauspicious start -- before 7am Arabella had sat on or fallen butt-first on the dishwasher door, so now it opens a little too far and the front is hinky, and then she pooped on the bathroom floor, unintentionally I am sure. This morning has been worse, it's not yet noon and she has had 3 time-outs (2 for hitting me, one for screaming that she wanted to go outside after a long battle wanting to come in). I've had to threaten to cut off all movies and tv several times, for things like playing "soup" with real water and real mixing bowls and her breakfast, all over the kitchen floor. Is it too late to trade her in? Maybe for a pony. Or a slab roller. Tomorrow she is staying the day with the babysitter (her last day, sigh), so I will have a little break. And hopefully Tuesday Michael will be back, and I can at least hand her over when he gets home and say "I'm going out for drinks."
