Prudence: Your highness（殿下）, a princess never prepares her own meals. That is not how things are done.
Cinderella: There are rules about breakfast?
Prudence: Of course, there are rules. But it’s certainly not your fault that you don’t know the traditions of the castle（城堡，皇宫）. That’s what the king expects me to teach you.
Cinderella: I am sure I can learn it in no time.
Prudence: Mm-hmm. Come along. There’s no time to dally. Just do as I say, and everything will be fine.
Prudence: The king would be horrified to find the hostess of the royal banquet（宴会） dressed like a scullery（洗碗室）maid（女仆）! A princess must be attired（用鹿角装饰） like royalty.
Cinderella: Couldn’t I just wear one of my own dresses?
Prudence: Very amusing, Your highness…but it simply isn’t done.
1. This is how things done. 事情应该这样做。
2. I can learn it in no time. 我会很快学会的。
3. There’s no time to dally. 不能再耽搁时间了。
4. It simply isn’t done. 这可不行的
