Okay... I can not take credit for this. My friend, Frost (the one that I moved away from... D: ), made this. Oh! And she said the moral was... I will not tell you! You have to wait and read. :D
One day, during newleaf, there was a Queen named Mousepelt, who was gossiping like a couple of elders with some other Queens, was distracted... too distracted to pay attention to her five moons old kit, rabbitkit. 'Can I go to Bloodclan, please,' said the little gray kit to his mother.
'Sure, do whatever just don't interupt my conversation,' said his mother unknowing what she had said yes to.
'Okay! I will kill you later!' he said enthusiastically and quietly added, 'I promise,'
A several moons later... "I am finally back" thought the big warrior, who had been born in Thunderclan but moved to Bloodclan at five moons old, now called Rabbit. As he arrived at Thunderclan camp he saw his mother walking out alone to hunt. He waited patiently while she went far away from camp... soon she arrived ten tail lengths from fourtrees. Then, he popped out at her and pinned her down. 'Listen to me!' hissed Rabbit into her ear, as she struggled to get free. She screamed untill she realized no cat could hear her, she finally stopped and settled down.
'Fine I will listen, but why do you want me?' said Mousepelt
'I keep my promises,' the gray warrior said casually, 'and its you because I am your son, who was once Rabbitkit but now Rabbit.'
'What was the promise,' said the worried warrior.
'To kill you,' he spat. And with that he killed her.
And the moral is... DON'T MAKE PROMICES YOU CAN'T KEEP! XD
