I have my own story intimately related to this day. When I was a young girl of about 8 or 9 years old, I had lost my gold cross while at school. Three days later, on September 14, as I was walking on the sidewalk of the school, a black girl came towards me, holding the cross and asking me "Did you lose this cross?"
I was so happy to see it, because it had been given to me by my godmother and had several delicate carvings that make it unique to other crosses. I thanked her and took it. I never saw her again.
When I returned home that day from school, I told my mother the story and she became very, very happy. She being a reverent Greek Orthodox christian said "This is the Day of the Holy Cross! It is a sign! You lost the cross three days ago and now it was given to you. You were meant to have this cross given to you."
So I do believe in miracles, especially on this day.
