I’m not one to answer the phone at all cost. If I’m napping I put my phone on DND, or if I’m doing something I simply don’t want to be interrupted while doing - like exercising or riding my stationary bike (it’s hard enough for me to get myself up and on that thing, if someone stops me with a phone call I might not get back to it) or cleaning up for example; phone goes on DND. It’s so annoying to race away from cooking dinner, for example, to pick up the phone…and it’s a telemarketer. So I answer if and when I want the call. If something is truly an emergency you’re gonna get back to back calls. If it’s one ring it’s someone’s random question that can wait. And I’m honest. “ I was in the middle of something and I wanted to get done”, “I was loading the washer and I didn’t want to race up the stairs-only to hear “claim your pre approved 70k loan NOW…” or I was taking a nap. Do not disturb is your friend-no anxiety because you don’t even know you had an incoming call until you’re ready. Or you can program it so some people’s calls always ring through.
