Talk safely to me

One of the main uses of Internet nowadays is definitely communications. From chats in cellphone apps such as Whatsapp to E-Mails, Snapchat Videos and Tweets. Let me define it as “every singe interaction that can is meant to be read by another internet user“.

Some days you just cant get rid of a bomb.
