The kids certainly don't. During the week, they'll ask us "How many more days of work?" And when it gets to be just a couple, they'll ask how many more days until Disneyland. And the night before we go, they still get excited and tell each other "Tomorrow is Disneyland!"
Last night they were both still excited as they were going to sleep. T told them to think of other happy things, like rainbows and puppies. "And cows!" said Ian. "And Disneyland!" said Alli.
