Hey Japanese people.
So you guys are already contaminated with the radiation?
Isn't it just scary?
Well I'm guessing that devastating earthquake is going to
hit Tokyo and kill a lot of people,
which I really can't wait for it.
I'm always thinking Japanese people dying, but I can't kill them
directly, so it was really exciting to hear that Japanese people are
dying from the natural disaster.
Well, im going to stop here and watch Japanese suffer more from
the earthquake.
Hope you guys die soon.
