Really?
Really?
Have you never met any kids?
This is exactly the kind of thing kids do. They get all excited and then calm down and think, "Hey! What about my snack?! I want my snack!"
They're kids. And they tend to exaggerate.
Neither my sister or I have perfect DIS children.
I'm sure perfect children would sit quietly in the backseat so delirious with joy over leaving for Disney that they wouldn't even think of their snack, much less become Drama Llamas who state they will die if they aren't fed until dinner.
We don't have those kind of kids. We have the normal, average kids.
So sue us.
I had something happen to me similar when we surprised our daughters when they were younger. I have a video of me waking up our then 3.5 year old at 3am for our flight and telling her we were going to Disney. She got excited then looked at me and asked if we could go later so she could sleep.
We once told DDs that we were driving MIL to the airport as she was visiting Disney with friends. When we got to the airport we told them, we are the friends! That time they were both yelling with happiness.
