In a world where we're all in contact with each other all the time, sometimes it's impossible to reply to all messages straight away, no matter how much you may like the sender. Given that many people view being left 'on read' as a bit of a faux pas, the pressure piles on to reply as soon as you open a WhatsApp message.
For those who feel anxious as soon as those two little blue ticks pop up, there is an answer to your prayers, and it may buy you a bit of time before you need to formulate a response.
Many WhatsApp users may not be aware that they can read messages in full without opening them, alleviating some of the unnecessary stress.
