digital camera

About one week ago I requested my sister to buy a digital camera for me. She knows much more information about camera than I know. Today she called me and told me that the camera has arrived. I was so excited and desired to get my camera as soon as possible. But it needs almost a month that I can go home in Taipei and get my camera. Before I go home, my sister said that she will use the camera first then tell me what should I beware. I hate that I am not the first person to open and use my own thing.
