‘‘People are very reluctant to talk about their private lives, but then you go to the Internet and they’re much more open.’’    - Paul Coelho

The writer, I think, tries to explain the irony many people face every single day. You meet people, and you want to know them more. When you ask them what you want to know about directly, it’s inappropriate. On the other hand, you can just use the Internet for this. Do you want to know where they go? Look at Swarm. Do you wonder about their hobbies and if they have a relationship or not? Check their Facebook account and relationship status. Also, you can check their Instagram profile. Do you want to know about their favourite music /religious ideas? Then you should definitely check out their Soundcloud/Spotify/Fizy and Twitter accounts. And there you go, you know even more than you needed, only via Internet. I definitely agree with the writer. People should realise that anything they put on the net or apps stays there. If you don’t want others to know about you, then don’t use the apps like your personal diaries.
