For me, making a phone call to someone I don’t know, is terrifying. I can’t hear most tone of voice, so anything beyond the most basic emotion, tone of voice is lost on me. Like, you’re laughing? Crying? Screaming at me? Gotcha. Happy/sad/angry respectively. Beyond that? My brain doesn’t really register it at all. Not in real time. Not effectively enough for conversation or to pick up on anything remotely subtle.
Add in that I can’t see their face/body language to get even a feeble read on that, plus the inability to make predictions about the direction of the conversation due to the lack of this information..
Its like being lost in a foreign city in the middle of the night. And when you ask for help, everyone just says, “You have the address, you’ll be fine. There’s nothing to be afraid of.”
