SO I dropped my wallet in the train, and when I bent down to pick it up, I accidentally released a  loud fart. Worse of it call, there was lady who was sitting and heard it! 
It happens to the best of us! I know the lady understands!
I hope so, she pretended not to hear but I know she heard it. It was just so embarrassing and left me red faced! 
Maybe you'll never see her again!
