My wife and I have one cellphone and we don’t use it unless there’s a compelling reason. Babbling with friends or relatives is not a compelling reason. It’s turned off probably 95 percent of the time.
We still like our land line which gives us a household phone, not an individual person’s phone.
Turning your phone off only keeps the phone in standby. You need to pull the batteries if you actually want it off. But they thought of that and made the batteries inaccessible.
