That's natural. The other person is probably equally nervous. The more we practise, the less nervous we get. Let's try talking to each other.

I'm guessing you want to meet a foreigner and have a conversation with them. You might ask where they are from? What do they do (are they working/studying)? Perhaps, ask how long they have lived in China. If they are new to China, maybe you can tell them something interesting about it. If they have lived there a long time, you might want to find out why. Really, you can ask just about anything that you might ask a Chinese person you are meeting for the first time. However, I would suggest you don't say anything about their appearance or ask something like how much money they make or what their opinion is about politics when you first meet. Students often comment on how "white" I am or how blue my eyes are or how beautiful my wife is. Those sorts of comments often make me feel uncomfortable and not eager to continue a conversation. But if you find a topic that I am interested in, I am eager to potentially make a friend.

你好啊。 今天怎么样？ Hello. How are you today?

I can understand that, when talking in English I just don't know how to express my idea.
