You now have emails and text messages that are delivered faster than the handwritten letters. You can send emails and text messages instantly using your computer or mobile. These ways of sending messages are very easy. But no matter how convenient they are the handwritten letters will not completely vanish.
There are many people who still prefer the traditional way of writing letters. They want to preserve this practice of exchanging letters through the post office. People of the old generation still prefer this way of writing letters.
For personal touch
No matter how well you write your email or text message, you won’t get the personal touch that you get by writing letters. In the past, people who were in love with each other used to exchange letters. The paper used to write the letter, the pen used, etc. were considered important.
Most of the formal letters are still delivered by mail. The only difference is that these are now typed instead of handwritten. So, for sending formal letters, there is no alternative to the letterbox letters.
Technology is constantly improving. In future, you will have other better methods of communication. But it is sometimes difficult to break the tradition. The number of people using the traditional form of letters may decrease, but this old way of writing letters will never vanish.
