Why do you find it difficult to resist the temptation to share snaps or messages that you’ve just seen? Some of the common excuses are: time pressure, lack of privacy or your parents’ disapproval. Well, it wasn’t always like this. A few decades ago, that motivation would never have caused you to stop sharing! Thanks to Snapchat, it is now easy to take a few moments to snap a photo or send a text and share it online.
