Texts are easy to forget and difficult to write? Disagree. Texts are easy to remember and can be viewed back at any time. Writing is a bit slower than speaking, but at least it allows you to think about what you’re saying. There’s definitely a place where speaking is preferable, but then it should be in person or via a laptop video/voice call so the quality is better and I can do other stuff.
Most people call me to get some information or to push some information to me. Unless they need the answer now I want a text message of some sort, not a call. I’m okay with people like my parents calling at a predetermined moment to catch up. But most people who want to call me want to do so at a moment when a text message would be hugely preferable, so I don’t answer unless I get a reason (via text) why the call should happen now. In many cases this leads to the conversation going much more efficiently via text and allows me to actually defer it to when I have time or energy for it.
