For me, it is always when someone asks me a question which answer could easily have been retrieved through their phone online. You’re meaning to tell me, that what you have in your pocket, is not some form of gateway to information that can answer anything you’re curious about at just about anywhere?
So you go and bother me instead, whom for all I care, could just lie to you or to be honest, admit that I don’t know everything. Because that’s what your god damn phone is for now and has been for a while now. Go use it, stop nagging me, I know when to use it when I want to know something, I don’t go around bugging people and asking stupid questions.
I don’t think it’s very common, partners and flatmates have definitely (and understandably) been frustrated. When I was younger and used to smoke, my friends would be horrified that I wouldn’t tap ash into the an ashtray, but just into the floor or couch I was sitting on. It wasn’t intentional, I don’t like getting ash over myself (or having to pick up envelopes, or find socks scattered over the house) but if I was occupied by a conversation or even just thinking about something, it would happen without my noticing.
But to be fair, I have adhd, so I’ve got a bunch of issues around attention and impulse control. It’s a tiresome habit, and I’m definitely not condoning it. I’m just so glad that I don’t act like that outside my home. There I’m just normal levels of thoughtless, like forgetting to use coasters.
