We have had an office thief for the past month. Many of us have discovered money is missing from purses or backpacks that were left in our desks. We haven’t been able to figure out who the culprit is, but for some reason a few people suspect me. I am guessing it is because the thief has not taken anything from me. I am not the thief, I swear. I would not be writing to you if I were. How can I convince them that I did not do it?
