Why do people nowadays prefer to send text messages rather than make phone calls?

From the perspective of communication context, in face-to-face verbal communication activities, because both parties are in the same time and space environment, it is difficult to hide the feelings of the subject in the communication process, and both parties often have to observe and observe the words instead of saying whatever they want. Even for telephone communication, although the space distance can be far away, the time is still synchronous, and two people must hold their mobile phones at the same time. Also try to figure out the emotional meaning of the other person's voice (dissatisfaction? Aren't you happy? Jealous? Spoil? Wait a minute. ); However, in the short message communication, the two parties are not only in different spatial environments, but also in different time environments, and there is a flexible time difference between receiving information and sending information.
