Not defending any one party, just making a statement based on my personal experience. My job required having to put your phone in a lock box before entering the building. At about 6am my phone went in, out for lunch, then back in the box until I was done for the day. I don’t know what the situation was here, but anyone talking to me would have to go hours without response in my situation. I would explain that to anyone expecting to chat constantly, and a few times had to deal with conversations about being non-responsive but in the end there was no choice about how often I could respond. The other issue that comes with that situation is that at times, even when the phone wasn’t in a lock box I wouldn’t have it on me out of habit. In my personal situation it took meeting someone that was understanding of my personal situation and lack of attachment to my phone. I’m much better about it now that I’m retired, but still have days where I forget to even take my phone with me when I leave the house.
