At the Post-Office
If you want to buy stamps, postcards, envelopes, to send a telegram or money order, to subscribe to newspapers o magazines, you have to go to the post-office.
At some post-offices there is a special window where you may pay your rent, telephone, gas and electricity bills.
Yesterday, I had to send a parcel to my friend in another city. So I went to the nearest post-office. I handed the package to the clerk at the window marked “Parcel Post”. She weighs it and I paid for the stamps which she stuck on the package
Then I went to the next window marked “Stamps”. I had to queue up there. When my turn came, I bought writing paper, envelopes and a few stamps. I sat down at a desk and wrote a letter. When the letter was ready, I wrote the address on the envelope, stuck a stamp on it and dropped it into the nearest letter-box.
