Prudence: Your highness, 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. Your highnss. But it’s certainly not your fault that you don’t know the traditions of the castle. 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 dressed like a scullery maid! A princess must be attired like royalty.

Cinderella: Couldn’t I just wear one of my own dresses?

Prudence: Very amusing, Your highness…but it simply isn’t done.

scullery:后厨房，洗涤室
attire:穿上盛装
banquet:宴会
I can learn it in no time. 我会很快学会的。
There’s no time to dally. 不能再耽搁时间了。
It simply isn’t done. 这可不行的
