The girl who lost her wallet

It was a Saturday afternoon and I had been out for a stroll in downtown Chicago. I was waiting for my train when a girl approached me. She said she's one dollar short for her Metra ticket to Joliet and asked if I had a dollar...

Then she continued talking to me and said she lost her wallet. I asked her "how did that happen?" and because she didn't expect me to ask she made up a story how she had to "fix her pants" and when she did, her wallet was gone from her back pocket...

I knew she was lying about everything but I still gave her a dollar...
