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   memories. And receiving mail through a mailbox outside our gate was just as exciting.
My small hands could    get the mail without using a key! I always could never    to see how much I was getting. Oh, a letter! From Singapore! I would run back home and show it to my     . 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      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    with five friends on top of the mountain in Longsheng, China. At sunrise we   up to a beautiful view from the mountain top. Later in the afternoon, as we were going    the mountain and returning from the sunrise viewing place, a small  caught our attention. It only sold noodles, coffee and had a China       sign.
We asked the owner if she could really send mail. She happily said yes. It seemed hard to believe,    we were at the highest top of the mountain. I picked one postcard out and asked my friends to write    a birthday note. We bought a stamp, wrote some notes and gave the shop owner the postcard.
Three weeks later, I arrived home and     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   the post office all these years. Today I    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.
