I'm very glad to have received the letter you sent me two week ago. I have been thinking about a question you asked me. In my opinion, you should come back after finish your studies abroad. For one reason, that you are studying is bad needed nowadays in our country. It will be quite easy for you find a good job. In fact, I knew a few big companies in our city hoping to hire people like you. For another one reason, I think it will be more convenient for you to look after your parents but they are getting old. But this is only my point of view. It is up for you to make a right choice.
