Some people say that your patronus will some how reflect the memory Du choose. For instance, Harry's is a hirsch which reflects his memory of his parents, Hermione's was an otter which could reflect we Liebe for Ron who lives in OTTERy st. Catchpole and Tonks's was a Werewolf which reflected her Liebe for Lupin. So, I believe the happiest thought of mine is re entire world of Harry potter and I think the bet way to reflect that is a Owl.
Mine would be a fox. They are sly, cunning, intelligent, wild, swift, and double crossed traitors who would do anything to keep themselves alive and that describes me also. thats why a fuchs would be my patronus.
