You phone shouldn’t make any sound whatsoever when you’re in public period.

It can ring and give notifications, as long as they aren’t set to something obnoxious.

It becomes obnoxious no matter what it is when they’re having a text conversation with someone and it’s going off constantly

I’m pretty old but do you know the Woody Woodpecker laugh? I used to work with a girl back before smartphones that had that as her text notification. It was the whole thing which takes like five seconds so sometimes it was just that fucking sound almost non-stop. Here it is, cursed fucking creation.
