Hi I ❤️ HP, PJO, HOO,KC , Sherlock , DW, OUAT and lots lots more. 
That girl you just called a Mudblood?
She was once tortured because she is Muggle-Born.

That guy you made fun of for coming from a poor family?
He has spent half of his life competing with his brothers and friends trying to impress people.

That guy with the lightning scar you make fun of?
He lived in a cupboard for eleven years before he got a small bedroom.

That girl you called Loony?
Her mother died when she was nine.

The boy with the Rememberall that people make fun of? His parents suffered a fate even worse than death and they don't even recognize him anymore.

Post this on your profile if you are against bullying in the wizard and Muggle world.
