Sponge the absentminded
Today I flagged down a girl after my French class to ask her a question about the homework. As she pulled her notebook out of her bag, she dropped a pen on the ground, which I helpfully reached down to grab for her. We talked for a few moments, introduced ourselves, and I thanked her for the clarification that she gave me. Just as I was about to head off, she said, "Uhh, was that my pen you put in your pocket?"
