My dad and I were walking to the car and this bum casually rides up to us on his bike and nicely asks my dad if he would like to buy the bike. He said that he needed the money because his little kid had a doctors appointment the next day and he needed some cash to pay for the bill. My dad told him that he left his wallet at home and we got in the car and left. Just as we pulled out, I remembered that I had seen the bum at the bar around the corner. Turns out my dad really left his wallet at home and the bum never had a kid.
