People are more important than "your time", and a failure to realize that is a dehumanization of the other party. The latter response demonstrates emotional sensitivity towards the other person in the conversation. Among most people, that is important. It makes the other party feel good. It reinforces that you do care about the other party enough to ensure that they are not potentially affronted by terse communication. This is why normal people, lacking in the self-absorption your post exudes, do this sort of thing.
And in any case it doesn't take more than a few seconds to write or read; when the hell did four sentences become a "bloody novel"?
