Gryffindor : *sneezes*

Hufflepuff : bless you !

Gryffindor : I already am, I mean look at that booty.

Ravenclaw : *sneezes*

Slytherin, smacking them with a book : get the hell out of this dusty library !

Hufflepuff : *sneezes*

Ravenclaw, Slytherin And Gryffindor, in perfect unison, handing them a tissue : Bless You ! Are you cold ? Do you want my jacket ?

Slytherin : *sneezes*

Gryffindor : *stares at them*

Slytherin, without looking up : Bless me.
