Trust and Fear

I was at home, relaxing after the recuperation test, I called my mother to say to her that all went as good as it could be, I was starting to play at the computer as always, when someone called the house phone, I thought that was my mother to tell me something that she forgot to say earlier. But when I caught up the call, no one spoked and after 5/6 of silence, where I asked "Hello? Who's there?", then a whisper... "Goodbye" and there's finished the call.  This is the last massage of a friend, he's not a funny boy, is quite serious, on this things in particular. Has been passed 2 weeks, and he's disappeared, everybody is searching him, his family and his friends, at his home everything has been all left as it was, smartphone, wallet, money, EVERYTHING, nothing was missing, just the clothes that he had and him. Stay aware from the calls.
