If you send a message to a person, is the speed of its reply related to the degree of care or indifference?

not necessarily, because there are many factors that will hinder the response, such as the battery of the mobile phone, poor signal, or busy not looking at the mobile phone, etc., which will affect the response speed, so the speed of replying to the text message has nothing to do with the degree of care. Of course, if you reply quickly every ten times, you still care, on the contrary, you don't care ~
