If I had kids, maybe the "nothing is urgent" would be different, but I also know modern parents can't fathom the fact that I was never reachable during school, ever, and that was perfectly normal and fine.
Android let's you customize DND as well, so I don't even see new or existing notifications unless I swipe down. This means if I get my phone out to look something up, I'm not going to get distracted for 5 minutes.
Modern phones are a plague. Dates, parents, siblings, coworkers everyone seems to be oblivious to how often they will just drop out of a conversation midsentence because their phone buzzed or beeped. I just stop talking until they're done now, which inevitably makes them uncomfortable. Sorry, it's rude AF and I get tired of repeating myself.
