I regularly go about 2 ½ days without making a single audible sound with my voice. Friday through Monday.
I used to talk to myself a bit or sing/hum along while listening to music but I kinda stopped doing that.
The funny thing is, I’ve recently realizied that the last and first thing I say throughout the weekend are usually the same. I say “Goodbye” to my coworkers on a Friday evening, and then I say “Goodbye” to the cashier near the self checkout at the grocery store where I grab my lunch for the day on a Monday morning. It’s sort of ironic that the first thing I say after a long period of time, is something that usually ends a conversation.
Ive had a lot of jobs where i worked alone. Ive also had a few stints of prolonged unemployment and other random things that kept me isolated. I started talking to myself, just kinda about whatever i was doing. Sure i look crazy but it helps. Now i have co workers and stuff i bs with so its better.
