OOP: Sorting hat's song

[bibphile]

No: HPFGUIDX 63186

The song goes:


Said Slytherin, "We'll teach just those 
Whose ancestery is purest."

Said Ravenclaw "We'll teach those whose
Intelligence is surest."

Said Gryffindor, "We'll teach all those
With brave deeds to their name."

Said Hufflepuff, "I'll teach the lot,
And treat them just the same."


Why does Huffulepuff use "I'll" when everyone else uses "we'll"?  It
must mean something, but I don't know what.
