She doesn't see herself as a toddler!

My daughter doesn't think of herself as 2 years old. I know she really doesn't have a clue about her age and what it means. She thinks she's entitled, no matter what.
Some examples yesterday, all very cute:
She got in an argument with another girl yesterday. We are in the grocery store waiting in the checkout line and she's sitting in the cart seat as another family pulls up in the line next to us. They have a daughter not more than a year older than mine and a son who looks to be under a year old. My daughter starts giggling (she does this when she thinks something is cute) and says, "Look at the little baby!" The other little girl, who is walking, looks at my daughter and says, "Who are you calling a baby?" My daughter points to the boy and says, "He's a little baby." The girl says, "You're a little baby!" My daughter gets indignant and states, loudly, "I not a little baby! I a big girl!" The other girl retorts, "You're stuck in the seat!" My daughter rises up a little and yells back, "NO I'M NOT!" She's sticking up for herself! I was laughing, thinking the exchange was adorable but the other parents didn't seem to find humor in the situaiton. Oh well ...
A few minutes later, I'm writing the check after the girl tells me how much I owe. My daughter looks at the cashier and says, "I want thirty, ma'am." The cashier didn't hear her so she leans over and says even louder, "MA'AM, I want thirty!" The cashier looked confused so I just said, "Yeah, I wish it was thirty, too."
Last night we went out to eat and my daughter always thinks she can order her stuff, too. I ordered our food and my husband ordered his. The vegetable of the day was corn, so he asked for that as well. He added that we could use a few more lemon slices for her to gnaw on. (She loves them.) My daughter said, "I want some corn!" We tried to explain to her that she could have some of Daddy's corn, but she wouldn't hear of it. As the waitress was walking away, our daughter, fearing she hadn't been heard, yells after the waitress, "And I want my OWN corn. And some lemons!"
We know the owner of this restaurant and saw him as we were leaving. My husband told her to go tell him the food was good. She walked up to him and as he bent over to talk to her, she put her arm on his shoulder as if she were an adult talking to another and proceeded to use his name and tell him the food was good!
"What a cute little girl," a man at a nearby table said as he watched the exchange, "I bet she gets whatever she wants!"

I really think she thinks she's just like an adult! It is awfully cute, though!
