I can't believe one of my students died yesterday after the stolen car she was riding in crashed.
I can't believe another student was locked up for stealing a car.
I can't believe that I am hearing that he also got shot!
I can't believe the madness that is going on here at my school.
I can't believe that I have a headache right now

(I don't get headaches)
I CAN believe that there must be something really wrong for me to have a headache.
