Wow, grandma could have been a total hag witch and that is still disrespectful and mean. Keep them for yourself, lady! If she was that awful, the fact that you got them against her wishes should be enough, but methinks maybe the seller might just be the awful one and grandma (who is so conveniently not around to defend herself) may have just gotten sick of the bs. Grandma sure isn't the one pulling such an awful stunt!
