I heard Kiya complaining from the forest and underbrush below and behind me. I heard every word, including her made-up word "foopoof" which I assumed meant "poofoop". Although, she might have meant "foolproof", but then the context of the sentence would have been ...
WHAM!!
The pretty little birdies chasing the twinkling yellow stars in circles around my head, were tweeting to the stars that I had just discovered an invisible barrier. "That's using my head" I thought to myself approvingly.
Knowing that the others in the group would be equally impressed by my marvelous dicovery, I notified them with the traditional invisible barrier discovery vocalization:
[color:"pink"]"Ow ow ow ow OW! My head! My head!"[/color]
To emphasize the event for those out of earshot, I dramatically fell to the earth flailing my arms and legs, arching my back, and bouncing on the ground several times before rolling around holding my head with both hands, squinting my eyes, and grimacing to show both of my teeth.
They must have understood the message because they came running directly toward me and the barrier. I suppose that they, too, wanted to discover what the barrier feels like when you smash your skull into it.
