This is just some thought I had a while ago.
I think that history class must be really funny nowadays for the Hetalia fangirls, with all the Hetalia fandom around.
Now I wonder if something like that already happened in your class… xD
EDIT: Since some people misunderstood this, no, this comic does not state that laughing about historical tragedies is funny. It is just meant to be an observation of what actually happens in some classrooms. Without any judgement from my side. People just are the way they are and it may be either a good or bad thing but it does not change facts.
Besides, this is a parody, so no need to get upset.
