Why Did I Eat All the Cookies?

So yesterday, my siblings and I came home from school to find that mom had baked these delicious chocolate chip cookies. She left them out on the kitchen counter with a note saying not to eat them until after dinner because they were for our aunt’s birthday party tomorrow. Okay, fine. But as soon as she left for work, I suddenly couldn’t resist. First one cookie, then two, and before I knew it... I ate ALL of them! Why did I do this? Was it just the craving talking or was there something deeper going on here? Maybe because my sister always gets to eat more dessert than me? Or is it a control thing? Anyway, now there are no cookies left for Aunt Martha’s party. And what if she doesn’t like any of the other treats I offer? Oh man, this is such a mess.
