Life gets busy, I get it, but I also think that's one of the reasons people should be trying to prioritise mealtime as a focus for them to connect even if it's not possible every day. We used to go to my grandma's house every Sunday for lunch or dinner, it was only once a week but it was a really nice time (she was an awesome cook) and that one day a week is something I remember even after all these years.
I also think people should be finding time to leave their phone in another room, even when eating alone. There is nothing that important it can't wait 30 minutes and a person also needs a break from the continual bombardment of propaganda the phone (social media) delivers. Just my opinion, you're welcome to disagree...billions probably do. I just find there's more engaging things than staring at a phone screen all the time.
