This is a COW'S riddle
1.Her face was bright,
2.Now the slightest smile and soon she must go away for a while.
3.Sometimes I begin to call out her name,
4.She is ever changing and ever the same.
Who is she?
Answer:The moon. And if you're wondering what does that have to do with verse 3 its because it's a cow riddle!(e.g:Sometimes I begin to call out her name, Mooo...)
