The first time I met her, I was going upstairs. I said hello to her in Chinese because she appeared all of a sudden and I had no time to compose an English sentence in my mind.

The second time I met her, I saw she was opening the lock of her electric bike. In my hand were two sheet of English exam paper for the homework of this holiday, and a pen.
She asked me "Don't you sleep at noon?" in Chinese.
I answered "I just take this paper ...." (I forgot, sorry), in ENGLISH!
Then I said good bye to her.

When I was speaking English for the first time to my English teacher, I didn't feel nervous. Because in my opinion, there was no reason for me to be nervous. Since I could speak English a bit fluently, I should be very proud of myself. I should be happy rather than be nervous.

When I spoke English, the English teacher was very happy and smiled. Although when she was replying, she got stuck in the last word for a few seconds...

Even if what I say is grammatically incorrect or not so interesting, it does not matter. The most important thing is that I shouldn't feel very nervous when facing people. Instead, I should be very proud of myself because I can speak English.

There were a few questions that occurred to me but I didn't asked her at the moment:
Is that your electric bike?
What were you doing in the teaching building? Were you having lunch?

But it is important that the sentences immediately occurs to me as soon as I meet people and feel like speaking.

In other words, I should compose English sentences in my mind very fast, and then say it without nervousness.

The first time I met her, I was going upstairs and she downstairs.

Another way to avoid nervousness is to think that you are showing off your English skills to your friends and looking down on them.
