The difference between the four houses can honestly be seen quite clearly.
After/during an argument with a Hufflepuff, they will sit in a chair not leaving the room and not making many remarks.
After/during an argument with a Gryffindor, they will yell back bravely and stop out the room, slamming the door behind them.
After/during an argument with a Ravenclaw, they will make logical remarks, therefore making you annoyed to the point of leaving the room on your own.
With a Slytherin, they will make cunning remarks, eventually stomping out the room, leaving the door open just to annoy you because it makes you go shut it.
