Nah he’s just always had no self awareness when it comes to the noises he makes. Lots of loud chewing while you’re trying to eat, grunting and snorting in the middle of a conversation, full-volume “whispering” in movie theaters, etc. He’s not even hard of hearing or anything (dude hears like a bat, honestly), he’s just a very loud guy lmao
I’m gonna be honest with you, there’s probably some red flags that your doctor saw that perhaps you’re unaware of. You say living in your van is a choice; are you being honest with yourself about that? Are you actually taking care of your hygiene this way?
Because one red flag I’m seeing is a van-dweller making a doctor’s appointment in the first place. Usually nomadic/hermitic people (as in, those who choose to live off the grid and aren’t doing so as a matter of circumstance) generally don’t go to the doctor, unless something is really wrong. So for you to show up in a doctor’s office at all is already anomalous in the first place.
It shouldn’t be understated just how important basic things like access to clean running water can be. And you’re using the words “van” and “SUV”, and not “RV” or “motorhome”, which leads me to believe that you aren’t taking care of some basic needs.
If you’re truly taking care of yourself and being healthy, then more power to ya; I’m honestly a little jealous of those who can live that life. But if you’re actually struggling, you should probably consider taking a look at the paperwork they gave you. Don’t get pride get in the way of getting help.
