I'm sending a letter to my friend by airmail. It's not insured or anything, but how do I address it, again?
Well, obviously you have to write the name of the person or business in the center of the envelope.
Okay. What next?
On the second line, you write the address you are sending it to. Good, like that.
I got it now. On the last line, I write the city it's going to and the district, right?
Don't forget to write the return address in the upper - left corner in the same manner as the sending address.
