Since i was a child I have been asking this question around. I got diverse answers but nothing discreet. Granny always said our souls reach god. Mom said we all become stardust. My teacher said we just become fossils.
Eventually I realized. Nobody really dies. A piece of them is deeply engraved in our souls. They are very much alive in the space in between their loved ones. In our memories, they are still warm. In the past our eyes project they are still breathing. In every keepsakes they have left we are together. In all the frames hanging out there they are still smiling.
No one really dies, Until every ounce of the memories tracing their soul are completely erased.
