Did it ever happen that any teachers or fellow students from your school died? (Speaking of those in here, who are already adults, I'm thinking of times when you were still at school as kids, teens or college aged young adults). And did any of them die after you already left school, too?
When I was in later classes of elementary school, one little girl from my school died - she got mumps or something like that and there were complications and two boys from the high school, with which our school shared one building, also died - one accidentally drowned in the river and the other one fell down from the balcony of the hotel, in which his class was spending the night when they were on a school trip - he tried to get to the room of the girls through the balcony but fell down and died.
Also, three of my teachers died - one had a stroke a month before I graduated from college, the other two - my German language and art teachers - died when I was already out of school.
