If I am allowed to travel alone and can only bring one thing to entertain myself, then I will not hesitate to bring my laptop. In my spare time, I will chat with my family and friends through the Internet and tell them about my trip. With a laptop, no matter how far I go, my family and I are close at hand. I can also play online games to relax myself. More importantly, I can study through the computer every day, because the computer is an encyclopedia that I can't finish reading. I can also record what I saw, heard and felt during the trip in the computer, as if I had a most loyal secretary around me. I think it is a wise choice for me to take my laptop with me for a long trip.
