Why you should be proud being in Hufflepuff

Hufflepuffs are just generlly good

Hufflepuffs has also produced the least dark wizards in history. Their kind demeanor can be a cause of this too. Every house has their evil people. Gryffondor has Peter Pettigrew, Ravenclaw had Xenophillius Lovegood and Slytherin has many (no hate to Slytherin) but Hufflepuffs? None, of what we know of.

Hufflepuffs also had the second most students that fought in the great Wizarding war. They didn't do it because of the glory or to feel good about themself. They did it because it was the right thing to do.

Another point is that Hufflepuff don't boast about their goals nor achievements
