When I was nine years old, I used to go to the post office with my mother, sending greeting cards to my aunt in Singapore. To me, these trips were really   16  memories. And receiving mail through a mailbox outside our gate was just as exciting. My small hands could   17  get the mail without using a key! I always couldn’t wait to see how much I was   18  . Oh, a letter! From Singapore! I would run back home and show it to my   19  . When there was a letter for me, I wouldn’t run—I would open it right there.
After my family moved back to Singapore, I    20  going to the post office. Years later, my company sent me to Shanghai, and the post office found me again. Two years ago I celebrated my 21  with five friends on top of the mountain in Longsheng, China. At sunrise we   22  up to a beautiful view from the mountain top. Later in the afternoon, as we were going   23  the mountain and returning from the sunrise viewing place, a    24   shop caught our attention. It only sold noodles, coffee and had a China    25  sign.
We asked the owner if she could really send mail. She happily said yes. It seemed hard to believe,   26  we were at the highest top of the mountain. I picked one postcard out and asked my friends to write   27   a birthday note. We bought a stamp, wrote some notes and gave the shop owner the postcard.
Three weeks later, I arrived home and   28  my mailbox: Hello, postcard! I broke into a big smile.
That birthday postcard attracted me again to the post office and all its delights. I had   29 the post office all these years. Today I   30  send postcards to friends. And every time I am at the post office buying stamps, I cannot help but smile—how one postcard will make its way across the world and brighten up someone’s day.
