You want to fold your letter, if it is on standard-sized paper, into even thirds. Once you fold your letter, slip it into your envelope.  Seal the envelope by licking it or using a sponge to wet the seal. You can also place a sticker or a piece of decorate tape over the front flap of the envelope for extra security and decoration. This is how the post office knows where to send the letter. First, write your best friend’s ful name on the back middle of the envelope.  If you don’t plan to mail the letter, you can simply write the name. If you do want to mail the letter, write the street number and name on the line underneath the name. On the next line, write the city, state, and zip code. In the top left hand corner, write your own name and address. Then stick a stamp in the top right corner of the envelope. When you put the letter in the mailbox, put the mailbox flag in the upright position so that your postman knows that you want something delivered.  You can also take it to the post office, instead of placing it in your own mailbox. This will decrease the time it takes for your letter to get to your best friend. If you include anything extra in your letter that makes it heavier, it is a good idea to take it to the post office to make sure you use enough postage.
