Answers to the Q of the "Mother Tongue"

There is no doubt that different generation has different ways of speaking, because different generation receives different education. For example, we usually use English language such as "hello " or "hi" when we greet others as English has became more and more universal in Chinese school now,but to our parents, the most familiar way to greet friends is using Chinese words.

In less formal situation,such as when we talk to our friends,we usually use "cause" in stead of "because". Sometimes, I may use the initial letter of the first name of my friend to call him/her, for example, I may call my friend Emily "E". When we response the sentences " thank you very much", we should say "you are welcome" in formal situation ,while saying "no problem" in less formal condition.
