A little. Well, more than a little. She likes to be in control of her environment, including, but not limited to, her brothers.
An example. The remote. When the three children are watching TV, she's holding the remote. Not necessarily watching the show of her choosing, but you'd better believe that she's the remote master. It even goes with her to the kitchen table, the bathroom and sometimes to the computer, which is nowhere near the television. Because someone might dare to change the channel without her knowledge or written authorization.
We had the opportunity to go to a restaurant recently where we were given a buzzer-thingie that tells you when to go get your food. It was in the center of the table. She spotted it, nonchalantly grabbed it and placed it near her food. I, being the troublemaker that I am, waited until she wasn't watching and stealthily moved it back to where it was. As soon as she noticed it had moved, she popped her little hand across the table and put it next to her. A little closer this time. In case.
