You've never read a message with the intention of responding at a later time? I do and if I don't flag it somehow (unread) I will easily forget about it.

Ah, for email, I use flags to mark them that I need to respond. I treat "Read" literally – that means I've seen it. Thanks for the explanation.

My Samsung phone allows the message to be sent to reminder. Iphones don't have something like that?

Then what's the point of having read receipts? Just have them wait until you send them a message

It’s not for the receiver to keep them from knowing you read it, it’s to build a queue of messages you want to reply to (anything unread will be easily marked in the UI for later revisiting next time you get a text or open the app). In this case, marking it unread wouldn’t need to affect the read receipt in any way. Really the unread feature is an ad hoc reply reminder flag.

Ooooh I see. Thanks for the clarification
