练笔当不辍：

铁鸟

When I prick a bubble, I find the grim facts behind the facade of gaiety.

The facts are at variance with goddess's story.

Maybe, I should think: Give me a break! I'll pass them all with flying colors.

But, I cannot.

Yeah, I am banging my head against the wall.

You bet! I take after my father.

And, I've all fired up about all the ideas.

I just want to fuck and kill some goddamned Japanese tonight!

铁鸟

刘邦：You are welcome. It's most commonly used. Certainly, depends on your situation, no problem is also commonly used.

曹操：If you give someone a hand（small help）, he/she thanks, then you say no problem（at all）. If you give someone big help, then you can say "you are very welcome". If you treat others having a dinner, they might thank, then you should say "my pleasure". My personal understanding, may be not completely right.

苍舒：thanx.

润之：You are very welcome, got it?

苍舒：Yes, I see.

刘秀：Sure, similar to OK, can be used interchangeably.

张良：“Thanks for your trouble”，给您添麻烦了；“Not at all, I enjoyed it”，不客气，我乐意为您效劳。

苍舒：我加班，别人说让我费心了，我说没关系。

萧何：Not at all is fine, no problem is also fine, no problem is widely used. 如对方说了很多感谢的话，因你帮了很多的忙，你可说Never mind。
