Kai says Last night, I went to watch a scary movie at the theatre at the mall..
The friend responds I thought you don't like scary movies..
Kai responds I still don't.  I sat on the edge of my seat the whole time, clinging tightly to the chair in front of me..
The friend responds Was there anyone sitting in front of you?.
Kai responds Good thing it was an empty seat.  Otherwise, I would have been so annoying for someone else..
The friend responds At least you sat through a scary movie now.  Last time we went, you left the movie after half an hour..
