first time in japan

Well actually its my first time to go abroad, everything its new for me. I even haven't been to an airport before. So, at october 2nd, that's 3 days before i left, my sister, her friend, my friend tika and I went to the airport, we did that so we know where to go and not get confused. It was a nice trip, we went there by using damri bus, it's quite cheap if you have to compare by riding a taxi, only 20 thousand rupiah per person. That's the first time i know that the airport of soekarno hatta is more like a mall than a terminal, there are stores everywhere and a lot of people passing by.
We then went to my sister friend's sister office's (do not get confused) she explain that i only can carried 20 kg in my baggage, but i can more stuff at the cabbin...aha...
We went back by damri bus after five, and that's when my friend tika realized that her cell phone has gone, how could it be? we always stay close, never parted to far, except for somebrief time, like in musola or toilet. I couldn't believed it, the pickpocket are so fast and unpredictable....so thats end the perfect not so day...i'm really sorry about your cell phone tika, and brand new too hiks..hiks...well a hope you didn't lose this one...
