Yeah but that assumes you know better than your recipient whether they should like to know that you’ve texted them. That’s a bad habit to get into.
Let people manage the settings on their own devices - whether they’ve forgotten to set their quiet hours is not your concern. Trust other people to take care of their own responsibilities. If they mess up, they deal with the consequences - it’s not your problem. If they feel the need to answer your text immediately when for you it wasn’t necessary, let them choose for themselves. Don’t presume to take that choice away from them.
It is my concern because relationships are built on trust. One can assume that everyone has a smartphone today and they know how to manage the settings on their devices. This is not the case. Technology agnostic - settings are either there or not. It is up to me as the sender and the one that would like to maintain respect, to be respectful with my communication. Which is to not begin or continue communication when it is not of the appropriate time.
