I have a big problem, my best friend is dead. Last night I went with Mireia and When we were walking in the streets of Girona, Mireia was beside me, and speaking about us. Suddenly, I saw how some small object, flying very quickly; When I turned and looked at her, she was already dead. We do not know where the object from, but my best friend now is dead.
Somebody can help me?
