The events leading up to this incident was a major catalyst, as the government cracked down on violent Chinese protests, and no other could be brave enough to stand in front of militarist machinery.
I think the seniors are sad because they didn't get to do all the other things that all the other seniors did before them. I would be very upset if i didn't get to go to senior prom.
