Lillian and Bobby
"Dare you to go in."
Two bright yellow eyes peered into the darkness of the Craiss Caverns from the entrance. The male dug his claws into the lip of the entrance and leaned as far forward as he could, keeping his feet firmly on the ground. After a moment, he turned to his companion.
"Dare you to go first."
"Not fair! I dared you!"
"Well, I dared you back," replied the Imperial, as if this solved things. It didn't; far from it, in fact, as he realized upon seeing the gleam in the female's eyes.
"Don't tell me you're scared," she said, hunkering down a bit and peering closely at him. Throwing her voice high, she fanned herself and whined, "Oh, look at me, I'm Bobby! I talk tough but I'm really a bit sissy!"
"I am not!" Bobby protested, his fur fluffed out with indignation. He didn't sound like that at all!
"Prove it!" was all the female said. She was smirking triumphantly.
"Fine, I will!" the male huffed. He turned again to the entrance and ducked inside as fast as he could, before he lost his nerve. Only once he was firmly in the dark, peering up at the silhouette of his laughing sister against the lighted entrance, did he realize what had happened. "Lillian, you cheat! You tricked me!"
Lillian only laughed harder.
