My favorite thing about early Internet forum culture was the default understanding that people live in different time zones and work off shifts or what have you and that some or most of the people engaged in an ongoing conversation were probably AFK while you’re online. You got mercilessly mocked for making a stink about someone not replying fast enough.

Read receipts are literally of the devil. If you send me a message and it takes me a few hours or days to reply to it, I’m probably asleep (from 8-9 am to 5 pm US Eastern) or spending time with my family or experiencing symptoms of mental illness or otherwise doing hot girl shit, and if I don’t reply fast enough for your tastes then sweetie that’s a you problem.
