How to ignore everyone on WhatsApp - and get away with it

Not everyone appreciates the ‘read receipts’ that accompany Whatsapp messages.
While the blue ticks helpfully indicate whether a message has been opened and read - they also make it incredibly difficult for the recipient to ignore the sender without them realising.
Not to worry.You can now switch off read receipts on Whatsapp using this simple method:

Turn on airplane mode on your smartphone before opening Whatsapp
The ticks will stay grey, and the sender will be none the wiser.
