We carry phones that track our every move, and could probably stop them with little faraday bags. Credit card bags are popular, phone bags are not, so I think most people don't care sadly.
Most of the time people contact me by instant message or comments for social stuff, and emails for work stuff. It's rare that I get a call that wasn't pre-arranged.
Actually I'd feel rude phoning someone without arranging it first. Not terribly rude, but a little uncomfortable. What if they are driving or in an important meeting?
So maybe phones are there to let me check messages and alerts when convenient. A huge proportion of the money you paid for that phone went on the data modem after all. It isn't really a phone means voice, or sound. But folders on a computer are not made of paper. It's just a word.
Not that I'd suggest putting your phone in a bag.
Then they don't answer it. It's called self control!
LOL
Literally as I typed that above my phone started ringing, I didn't recognize the number, answered it, and it was a spam call. Lasted 12 second. That's the only one in my "recent" calls, which go back to March 27th. What are the chances.
Things have evolved to this? How do you arrange the phone call? Call them to ask if you can call them :) ? If you have to think about it or are unsure, then don't call them.
I'm happy to say that my problem is different, I'm not fond of phone calls, but when I call them, they're thrilled.
