Dear Helen,
     Last Sunday, my classmates and I went to the park. I wanted to take some photos. My father was
out at that time, so I took his camera without telling him. Unfortunately, the camera was out of my bag
and dropped on the ground when I was climbing the hill. It didn't work at all. I put it back quietly after I
returned home. And I haven't told him till now. when I face to my father, I feel terrible. What should I
do?
                                                                                                                                 Yours,
                                                                                                                                 David
Dear David
