Who Was That Kind Stranger?

Joshua loves a good tshirt.  The snarkier the better.  I picked one out for him for Valentine's Day.  It had the Superman logo on it.
Last Friday he told me that he was cruising to Pre Chem and a young lady ahead of him dropped her pencil case.  Pencils scattered everywhere.  Joshua unzipped his sweatshirt to reveal the superman tshirt underneath.  He helped her pick up every last pencil, zipped up and ran to Pre Chem.  The crowd that had gathered laughed and cheered.
