I can't believe I almost cheered out loud when another 4th grade classmate of mine died in a car crash
Why would you be happy about that? Were you close to him?
Not really, no. I just felt great that he died.
Death is something that is very sad. It is wrong to feel joyous when a classmate of yours dies.
I just wanted to be able to say a friend of mine died.
That's not a thing you should ever want to say. The death of a classmate, especially so young, is not something you can be proud of. Try to think of how his family must be feeling.
