Loyal. Dependable. True. Just.
What an honor to be sorted into Hufflepuff! The house based on values and virtues over simply deeds. Not that the Hufflepuffs don't do anything worthwhile, it's just that here importance is based more on how you are, not what you do. Hufflepuff is all about acceptance. Since when is that a bad thing?
In Hufflepuff, there is a fallacy that the members are simply average, not good enough to get into the other houses. This is most definately not so. Just because Hufflepuff doesn't discriminate against people for not being good enough (or brave, smart, and ambitious enough), does not mean that the entire house is full of wimps, as people seem to think. While, yes. hard-workers are most likely to enter Hufflepuff, this does not mean there aren't other qualities. The fact that Helga Hufflepuff will take "all the rest" can and is seen as a bad thing, by some.
A Hufflepuff is loyal to their friends, trustworthy and patient, and often hard-working. One need not to fit all the criteria of a house to belong it it, nor not have any of the other House's values.
Last, I hope I need not remind you of Cedric Diggory, the one champion chosen for Hogwarts, over all the cunning Slytherins, brave Gryffindors, and clever Ravenclaws. You'd do good not to doubt Hufflepuff.
