MOBILE MANNERS Don't keep ringing someone unless it's an emergency. You've rang, they didn't answer. If it's important, drop them a message to call you back. End of. Don't ring ten different people of that household either. If they've replied with a message that they'll ring you back, don't ring again. Don't ring at stupid o'clock. If you're speaking to someone and they say they need to go, end the call. Don't carry on for another 10 minutes. Even if they don't say it, read the replies or the lack thereof and end the call. Emotional intelligence. Two blue ticks and no reply doesn't mean they are ignoring. People have lives.
