Say something

It's been a long time that I use English, no mention French.

Since I am from Taiwan. I live here and work here. 

Language is just for communication. I don't have any needs to communicate in different language. 

That isn't totally correct. 

Indeed, sometimes I reply some email in English. Most of them are the things that might be impolite when say it in Chinese. Or something that I don't know how to say it to my bosses. 

I think the Sociolinguistics may have an analyse for this act. 

It's time to bed. 

Good night.
