Double Suicide

A schoolgirl and a college girl decided to commit suicide. First, the college girl stabbed the schoolgirl in the navel with a knife. The knife only went halfway in. The schoolgirl then stabbed the college girl in the navel with a sword. After the sword goes through her back, the college girl pushed the knife all the way in the schoolgirl's navel.

Who will die first?

Great acting by the girls!
