One day， when Sunee reached her house， she saw a brown package（包裹）． She ran inside the house with her package and showed it to her grandmother． Sunee opened the package． As she did，she noticed there was Thai writing on the box． This package had come from her aunt in Thailand．

    Inside the box， Sunee saw something uncommon． It was a red silk umbrella． She had never seen anything like it! Next to the umbrella she found a silk purse （钱包）．They were both beautiful．

    "Shipping a package overseas used to take a lot of time，" said Grandmother． "Packages traveled by train and ship． It could take many months to get a package from across the ocean． How long did your package take to arrive？"

    Sunee and her grandmother looked at the postmark （邮戳）． It showed that the package had been sent eight days ago． "That's fast!" said Sunee．

    Her grandmother agreed． "We have resources （资源）now that we didn't have years ago． Now， packages are flown across the ocean． Because airplanes travel so fast， packages arrive very quickly． Now our economy （经济）depends on fast delivery （快递）!"
