Okay, so i sent a letter in the mail a couple of days ago. The 23rd of December to be exact, The envelope never made it to the destination it was supposed to arrive at. Today i remembered something VERY important. I forgot to write the name of where it should have arrived, all that was written was the address. Would that have been the reason of the mail not arriving to its destination? And why hasn't it been sent back to my house? I did write my address at the top left hand corner so why hasn't it been shipped back here? Will i ever see it again? Can anyone answer my questions??
