Today is the end of a month, the library is not opened.
In the morning, there were not any works for us, so I assisted an engineer of the Research & Development in our department. I helped to test the infrared for him. I shook it, shook and shook, again and again. I must tell the engineer when the system shut down. He will rewrite the procedure language! The action always recycles. In that time he told me about interpersonal nets and he persuaded me into studying English. He is the second person to tell me these things. Although I don't know him very much, but I understand these are very well for me.
