You have issues to deal with if you don't want people to know that you've read their message.
So? Anyone who knows you should be aware of the fact that you often can't respond to messages instantly. At least they'll know you've read their message, which is better than nothing.
I do not enjoy the younger generation that requires instant replies to their messages. I am in 4 hour-long back-to-back meetings. It happens. I don't reply to your messages instantly, and there's no use getting offended at me for not responding. On the other hand, it's a good way to make me never speak to you on WhatsApp again.
