This week I went to a High School graduation. It's the first graduation that I've gone to that the principal announced that 2 students in their class of 2012 would not be graduating because they had been stabbed to death (in 2 separate occurances). Another graduate did get up on stage but she had recently come out of a coma from some tragedy. Another member of my family noted too that this was the first graduation that he'd heard such tragic announcements.
An interesting note: The school Chamber Singers sang "Regina Coeli" by Mozart.
