"Hey Tom,
Are you gonna kill half bloods? I'm actually a half blood. When am I going to die?
Damiana"

Hello Damiana,
I won't kill all half bloods. Only the ones that annoy me. If I were you though, I really wouldn't push my luck because you have been known to be annoying at times. Still, how have you been? I've been researching all sorts of fascinating things. The restricted section of the library is an interesting place.

Sincerely yours,
Tom Riddle.
