You have to do double the work in conveying and listening - you lose things like the benefit of body language, and intonation of voice. Now compound that problem with trying to communicate with someone over a digital medium.
When it comes to conveying a message with other human beings you have to make sure to speak clearly, listen well, use unambiguous words, remember what the other person said, understand the context surrounding the conversation, read between the lines sometimes, pay attention to body language and intonation, comprehend cross-cultural differences, and so many more subtle intricacies.
Communication is hard 😖 (it’s ok, little buddy, we’re gonna talk about some tools to combat this).
