It is funny what happens with recipes, it might never have been yours, but once you start making it people start associating it with you. I have this cookie recipe that was my 6th grade teachers that my older sister got from her. I made it a lot when I was younger, and everyone says it is mine now. I never really cared about whose recipe it was; if I wanted to eat it at a family gathering, and no one else was making it then I would make it.
