Ma'am, you have a duck in your bag.
You see weird things on the metro, but this was the first time I saw a person with a duck. My first thought was that the girl was a local homeless person. However, she was speaking French in the Barcelona metro (in Spain), leading me to believe she was not from there. So that must mean she was a French tourist with a duck. Did she bring the duck on a plane? Did she travel there from France and capture a native duck? Was her friend turned into a duck and the was heading to a witch doctor to undo the spell? I will never know.
