I said, "No, something is going to happen." He told me to wait 10 minutes and if I still had the same feeling, I should change the ticket. I couldn't stop crying, so I bought a ticket for another flight and took off 10 minutes after that flight did. It made me appreciate so much that just being alive is a gift."
