At the beginning of my college life, I had no personal computer because my parents thought it was too expensive and unnecessary. However, after a month, I realize the importance of computer, therefore, I had to borrow a laptop from my roommates. I always borrow it in the Friday evening. As you know, after a long-time study from Monday to Friday, many students would like to relax themselves in the Friday evening, which means they would not use their computer to study as that I can avoid causing trouble for them. Generally, teacher would give us some homework online, especially some listening test. I had to complete these test in the Friday evening with my classroom’s laptop. I always feel shy when I do that. as you know, I need log in the website using my account and password, which may be recorded by system, but I do not want other person to know my password. And of course, the owner’s password will be recorded, too, and there were some personal documents in the computer, making me uncomfortable. It seems like I peer other’s privacy. Therefore, I bought my own computer in the third month of my college life.
