Think about it: a mother bird, exhausted from sleepless nights and the travails of labor, forces herself to pick up her spirits and look cheerful. She has no idea that what she's worked so hard to bring into the world are just "rotten little eggs" that won't develop into healthy chicks .... Do you want this kind of a scenario to come true?
試想：孵蛋的母鳥已經幾天徹夜不睡，疲累異常，卻仍強打精神，露出期待的神色；它完全不知道，自己辛苦產下的，其實是幾顆永不會孵育小生命的「壞蛋」… …。你願意這樣的景象成真嗎？
