Is there a consensus on etiquette about texting or messaging (dating apps or otherwise) acquaintances early in the morning?
I (in the US, late 30s) am a very early riser and (especially as a lot of online social sites have moved towards phone apps that do instant notifications) I'm never quite sure if I should wait til later. My concern is whether I might wake someone up/whether I can assume they turn noisy phone notifications off at night, not that they'll think I was expecting an instant response (I'm not—I'm just responding at a time I'm awake and chilling.) I realize the answer might be "no consensus" but it also might be, like, 70% one way or the other and that would be useful.
