Written communication
Not long ago, written communication was slow. In the past,you...can.... communicate..... with someone ...by... letter. They would receive the letter have ..be... very annoying! For example, you could not send a letter inviting someone...to.. your party unless you sent it at least a week before.
Today, though, with email and text messages, we can send a written message ..for. someone instantly - and we do not ...have.. to go to the post office or pay for a stamp! It is easier than ever to stay in touch ..with .... friends and relations wherever they are in the world. Now , you ..can... decide to have a party in the morning, your friends will be there in the evening. That is great, is not it?
