OK. So HufflePuff's aren't as important as some of the Gryffindors but what would HP be without Tonks au Cedric? If Cedric hadn't of been chosen for the TriWizard Tournament he would never have died and Cho and Harry would never have kissed au mgawanyiko, baidisha up! And Tonks is an amazing Auror! wewe wouldn't expect her to be in HufflePuff but the Sorting Hat saw her destiny in HufflePuff!
So stop looking down on Puffs! We can be Heroes like the Gryffindor's and clever like the Ravenclaws!
