Back From A Business Trip
Riddle: During the first week of July, Jenny came back from a business trip and saw that her house had been burgled. She called the police and told them the following story: "My business trip was supposed to be between the 29th and the 31st of the previous month, so I was supposed to be gone for three days. However, I returned just now and found my house in a huge mess! Someone must have robbed me!". Jenny was arrested for a false report. Why?
Answer: Jenny came back during the first week of July, so the previous month was June. She couldn't be away for business between the 29th and the 31st of June because June 31st doesn't exist; there are only 30 days in June.
