If you're fast at replying to texts, you won't be able to wrap your head around those friends who seem to respond in three to five working days - sometimes for something that requires a yes or no answer.
Of course, we all lead busy lives, but arguably, messages often take little effort to respond to, so many people will not be able to make excuses for their pals who "unapologetically ignore your messages while posting selfies on social media."
And one woman was so fed up of her mates who were "notorious for doing this" that she took to Mumsnet to ask other people what they thought of those who take a while to reply to WhatsApp messages.
