Have you ever accidentally deleted the files on your digital camera? I know many of us have done this. It's not like you can just re-do that cross country trip with little Rusty & Audrey.
I was recently reminded of the sinking feeling one gets while I was speaking to a customer on the phone. While explaining how to take better photos with the digital camera, I recommended that he make some room on his memory card since the new settings use more space/memory. Instead of moving the pictures to the PC, he had just deleted all. At first there was a long awkward silence.
