I think it's because I walk fast. And am incapable of whispering.
Technically, it's not really interrupting. It's more enhancing an already intriguing conversation. You know, adding teensy nuances of girlie-girl commentary, that clearly can only elevate the understanding of everyone else.
Might also be because the story is so good, so compelling, fabulously fascinating, and I just can't wait for the punch-line.
OK, so there's that.
About the loud talking: Once there was a princess. She lived high up in the cloud-covered mountains, next to purple daisies and rain-drop-filled sunflowers. The rest of the village lived far, far below. Deep in the heart of a green-and-orange valley. The princess was very wise. And super-cute. Every morning, the valley peeps would gather at the base of the sunlit mountain, awaiting their sparkling & magical morning greeting.
Moments of silence.
Then, in the far, far remotest distance, way up high, they heard their glorious princess:
"Happy fabulous Monday!" she'd glitter.
The jubilant crowd would cheer. And everyone lived happily ever after.
Moral of the story: princesses are obligated to speak loudly. For how else can they make sure everyone gets to share in a slice of star-lit magic?
