I love you, gentle reader, I really do, but I certainly won't give you my phone number. Why? Because then you'll call me. And this is how it'll play out:
However, the mind-numbing inefficiency doesn't stop after we finished our awkward dance of kolo. Unless I was sitting in front of my computer, I couldn't take notes. So, I now need to do that from memory, which, given the reason why I take notes rigorously during meetings (it being me not trusting my ability to recall arbitrary information precisely in the distant future), will be error-prone. Then I'll ask you about details we talked about, and you'll forget things too that I'll have to repeat to you. Most possibly there are other people outside of us who need the information we discussed as well, so now I take on the role of postman and write down our conversation for them.
People call because it'll be "quick". Unless both parties' day is a vast emptiness, it'll be anything but. I get it though, it's about not having to think: If you have to send an e-mail, you need to gather your thoughts upfront instead of using the other person as your copilot to navigate the matter. And thinking hurts, your brain starts to suck up glucose and every cell in your body screams for you to stop. You may also not be able to type quickly. Unless a disability prevents you from it, the better investment of your attention is to learn it though. You'll also feel like a hacker magician typing away blindly soon enough!
So, please, unless it's an emergency, send an e-mail (or any other message). Am I being selfish? I'm trying to be respectful not to interrupt you, and considerate of both of our times. Calling randomly is selfish, actually, since it says, "I want something from you right now, so throw away whatever you're doing and listen to me".
Needless to say, when it comes to family members and close friends, or urgent matters, calling is fine. This is about more of a professional setting. Arranged calls and meetings scheduled in advance are not what I'm talking about either.
I'll be looking forward to your e-mail!
