Hufflepuffs are just like Gryffindors because they are
a)virtuous
b)stay close to their friends
c)are moral (don't cheat like slytherins)
d) are smarter than Gryffindors (but not like book-worm Ravenclaws)
They are just not as brave as Gryffindors in the outer form....their virtue is mostly unseen..and they just are not as chivelarous as Gryffindors.

-)Cedric possess all of these qualities
