Do you think it is necessary to write letters in the mobile phone world?

It can be said that in today's era of information exclusion, the development of communication tools is changing with each passing day. It makes people more transparent and communicate more directly, but any new thing will show its unique advantages and disadvantages. Now all the communication between relatives, friends, colleagues and lovers is through mobile phones, or telephone calls or text messages, although this is very direct. It's convenient, but I always feel something is missing. In fact, if you think about it carefully, what is lacking is the true feelings conveyed between letters. In retrospect, people communicate mainly through letters. Although it is slow, every word contains the writer's true feelings for the recipient, and it is also a kind of happiness to expect letters from distant relatives. Therefore, in today's mobile phone world, writing letters is a must.
